[Bug] Renaming separate chat tab (eg Battle) breaks close button

[Cloud7050]

I play with my Battle chat tab dragged out as a separate window. I renamed it to "B", but this caused the "[ x )" button on the right end of the bottom chat bar to disappear. I then tried to click on the "[ [2] B]" part of the chat bar, but for some reason this closed to tab back into the main chat altogether.

I did notice that at that point (or after a few more renames to General and Battle, not sure), the click detection of the entire main chat bar broke, where my clicks were picked up as if none of the chats had been renamed, despite the buttons now visually being much shorter. Perhaps the close button for the Battle tab was hidden behind the Battle tab's chat bar button due to the "[2]" numbering not being taken into account for its width, then something about the weird chat bar click detection caused clickig the tab's button to be picked up as clicking the non-visible close button. Just a theory.
