"Join Chat Room" dialog goes off-screen on small window
See image:
The following warning is also printed in the logs:
(polari:29422): Adwaita-WARNING **: 14:04:02.501: AdwBottomSheet 0x7f2357dbfef0 exceeds AdwBreakpointBin width: requested 408 px, 360 px available
(I have the minimize and maximize buttons enabled on the screenshot, but this also happens with just the close button or with no buttons at all (tested under Phosh).)
