The left panel of trivabble widens when a long message is added to the chat
This is a regression I introduced. The solution to this problem, that I then removed, was to fix the width of the chat on page load. But this is not an acceptable approach since the browser can be resized, or the screen can be rotated.
A quick fix would be to set a max-width, but this still means that the width of the chat box can change. Setting a width could do. Setting a width that is set is too big, thanks to flex-box, should not be a big problem.
Finding the correct approach is not easy.
