Message bubble corner rounding doesn't take into account whether events have a tile

[robintown]

Message bubbles apparently try to square off the corners of bubbles that are touching. But if someone sends a message and then edits it immediately afterwards, the bottom left corner of that message will be square instead of round since it thinks the edit event will appear in its own bubble, when that is not in fact the case.

Conversely, if a reaction event from another user happens between two consecutive messages, the first message will have a rounded bottom left corner when it shouldn't.
