better chatbox stops chatbar from showing multiple lines

[moonfight1]

default behaviour is that when you type multiple lines, it shows a max of 5 of them hy vertically expanding the chatbox, but this doesnt happen with betterchatbox, so you have to scroll through a tiny chatbox

i think a good solution would be to have an option that disables custom height, right now you can set it to the default height but that doesnt disable the limit being that same height
