+Subject: [PATCH] Fix failing cases for Python 3.14
+
+New change requires us to monkey patch `locatetagend` to prevent
+capturing incomplete tags in code spans.
+
+Upstream: https://github.com/Python-Markdown/markdown/pull/1548
+(released in Python-Markdown 3.9.0)
+
+The `docs/changelog.md` hunk of the upstream commit is dropped as the
+file is not shipped in the sdist used here.
