Closes: #1994

Description

Reworks the user message bubble in ChatRow to recover vertical space in the constrained chat panel.

Repeated "You said" / "Zoo said" headers occupy a separate line plus surrounding spacing for each message, reducing how much actual content fits on screen. Removing these redundant header rows makes more of the conversation visible at once and reduces the need to scroll, while alignment, bubble width, and background color distinguish user and assistant turns.

  • user_feedback: rendered as a right-aligned w-fit bubble (max-w-[70%], ml-auto, items-end) with no header label; edit/delete buttons move below the bubble; uses soft list-hoverBackground/text-foreground when not editing and keeps editor-background/foreground while editing.
  • user_feedback_diff: diff bubble aligned to the right (max-w-[70%] ml-auto).
  • text: drops the "You said" / "Zoo said" header label and distinguishes turns by alignment, width, and background color; the markdown preview button is absolutely positioned in the top-right corner.
  • Removes now-unused User and MessageCircle icon imports.

Reviewers should note that turn identification now relies on visual alignment/background rather than an explicit role label.

Test Procedure

  • Unit tests: cd webview-ui && npx vitest run src/components/chat/__tests__/ChatRow.user-feedback-bubble.spec.tsx
  • Visual snapshot: run the visual-regression suite and confirm the committed chat-row-* snapshots match.
  • Manual: send a message and an edited message; confirm the right-aligned bubble, correct non-edit/edit background colors, and button placement below the bubble.

Pre-Submission Checklist

  • Issue Linked: Closes upstream issue [ENHANCEMENT] Distinguish user and assistant turns without per-message role labels #1994.
  • Scope: My changes are focused on the linked issue (one major feature/fix per PR).
  • Self-Review: I have performed a thorough self-review of my code.
  • Testing: New and/or updated tests have been added to cover my changes (if applicable).
  • Visual Snapshot (UI changes only): Added ChatRow.visual.tsx and committed chat-row-* snapshots in webview-ui/.
  • Documentation Impact: I have considered if my changes require documentation updates.
  • Contribution Guidelines: I have read and agree to the Contributor Guidelines.

Visual Snapshots

Added webview-ui/src/components/chat/__tests__/ChatRow.visual.tsx (with ChatRow.visual.fixture.tsx) and committed baselines:
chat-row-user-actions-dark.png, chat-row-user-actions-light.png, chat-row-assistant-preview-dark.png, chat-row-assistant-preview-light.png.

Videos (interaction / animation only)

N/A — the change is a static layout/contrast adjustment covered by the committed snapshots.

Documentation Updates

  • No documentation updates are required.

Additional Notes

This PR covers only the user-bubble / unlabeled-turn portion. Turn identification now relies on alignment and background rather than a per-message role label.

📝 Summary

Summary by CodeRabbit

  • Improvements
    • User feedback messages and diffs are right-aligned and displayed in more compact bubbles, with clearer separation between message content and edit or delete controls.
    • Edit and delete controls stay hidden while a message is being edited or streamed.
    • Assistant text messages no longer show a speech-bubble icon or “Roo said” header; the markdown preview button appears over the message content.
    • Expanded user-edit details remain available alongside the conversation, with clearer content and improved readability.
    • Selecting a mention opens it without triggering message editing.
📝 Summary
📝 Summary

Walkthrough

Chat rows now distinguish user feedback through right-aligned, width-constrained styling and render assistant text without a role header. The markdown-preview button appears over assistant content. Updated tests cover rendering, controls, mention clicks, and visual states.

Changes

Chat row presentation

Layer / File(s) Summary
Chat row rendering and behavior
webview-ui/src/components/chat/ChatRow.tsx, webview-ui/src/components/chat/Mention.tsx, webview-ui/src/components/chat/__tests__/ChatRow.user-feedback-bubble.spec.tsx
User feedback is right-aligned and limited to 70% width. Message text supports keyboard activation for editing, while edit and delete controls are hidden during editing and streaming. Assistant text has no role header, and its markdown-preview button appears over the message content. Mention clicks stop propagation. Unit tests cover these behaviors.
Conversation fixture and visual coverage
webview-ui/src/components/chat/__tests__/ChatRow.visual.fixture.tsx, webview-ui/playwright/gallery/stories.tsx, webview-ui/src/components/chat/__tests__/ChatRow.visual.tsx
A three-message conversation fixture is registered as a gallery story. Playwright tests apply dark and light themes, check visible content, and capture screenshots with user actions and the assistant preview hovered.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature · Severity of issue fixed: Low





Merge Risk: 🟡 Moderate · up to cf1eb

Screen-reader users may be unable to identify who sent a message or hear the user’s message text. Long assistant markdown can overlap the preview button. Address the accessibility issues before merging.

Full details: Regression Evidence

Explanation

The PR adds custom keyboard behavior for the user-message bubble, but the focused tests do not exercise it. ChatRow.tsx:1257-1275 adds role="button", focusability, and Enter/Space handling, while the new spec only uses mouse clicks (ChatRow.user-feedback-bubble.spec.tsx:107-175) and checks that action controls are <button> elements. No test activates the bubble with Enter or Space, and no test activates the edit/delete buttons through keyboard input. The Playwright snapshots cover the visible layout and hover states, not keyboard behavior.

Resolution

Add focused keyboard tests at the component-test layer. Focus the non-streaming user bubble and verify both Enter and Space enter edit mode. Focus the edit and delete buttons and verify keyboard activation triggers the same edit state and deleteMessage payload as mouse activation. Keep a streaming case that verifies the bubble is not focusable and keyboard input does not enter edit mode.

Add an accessible sender name to each unlabeled turn.

ChatRow wraps ChatRowContent in an unlabeled div, and ChatView renders ChatRow directly for each message. The text and user_feedback branches also use unlabeled div roots. After removing the visible headers, screen-reader users cannot identify the sender. Add a localized accessible name based on message.type without restoring the visible headers.

1209-1212: Duplicate: Add clearance for the absolutely positioned preview button.

The absolute top-0 right-0 z-10 button overlays the markdown content. The content wrapper adds no right padding. A long first line or heading can render under the button when the button is visible. Add right padding, or a similar reservation, to the content when the preview button renders.


1255-1264: Duplicate: Make the message text edit trigger keyboard-operable.

The div with onClick has no role, no tabIndex, and no key handler. Keyboard users cannot enter edit mode from the message text. Use a button element or add equivalent semantics.


1257-1262: Duplicate: Mention clicks also trigger edit mode.

Mention calls vscode.postMessage without stopping propagation. The click bubbles to this handler and calls handleEditClick(). A user who opens a mention also enters edit mode. Ignore clicks that originate inside a mention, or stop propagation in Mention.


1209-1224: Duplicate: Add an accessible sender name for unlabeled turns.

The visible role headers are removed. The text and user_feedback roots expose no sender to screen readers. The issue requires screen-reader accessibility. Add a localized accessible name based on the message role.

90-107: Duplicate: Assert action behavior, not only presence.

The test finds the edit and delete icons but never activates them. Click edit and assert edit mode. Click delete and assert mockPostMessage receives { type: "deleteMessage", value: 1 }.

- Replace the edit/delete div wrappers in the user feedback row with
  button type=button controls that carry translated accessible names,
  reveal on focus-visible, and keep their stopPropagation click behavior.
- Make the message text bubble a focusable role=button so keyboard users
  can enter edit mode, with Enter/Space activation and an aria-disabled
  state while streaming.
- Stop mention clicks from bubbling into the row's click-to-edit handler
  so opening a mention no longer enters edit mode.
- Update the user-feedback spec to assert behavior (deleteMessage payload,
  edit mode, mention propagation) instead of only element presence.

The i18n keys exist in all locale files.

The inspected locale files define confirmation.editMessage and confirmation.deleteMessage in common.json, and queuedMessages.clickToEdit in chat.json for every locale. The missing-key concern is not supported.

Add keyboard regression coverage for the feedback bubble.

The changed tests cover only click activation. They do not exercise the new Enter and Space handlers or the keyboard isStreaming guard.

Add tests for Enter and Space entering edit mode, another key leaving edit mode unchanged, and Enter being ignored while streaming. Assert that ChatTextArea appears or remains absent in each case.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

aria-label on the message bubble hides the user's message text from screen readers.

The bubble has role="button". An aria-label on a button replaces its text content as the accessible name. Screen readers therefore announce "click to edit" and not the message. The linked issue asks for screen-reader accessibility after the role labels are removed, so this is a regression for those users.

Remove aria-label. The Mention text then becomes the accessible name. The title on Line 1276 still gives the edit hint to pointer users. If you want a spoken hint, use aria-description, or aria-describedby that points to a visually hidden element.
