Hands Up keyboard shortcut breaks if chat window opened

[GavinGaunt]

It is really great that you have introduced a keyboard shortcut (Ctrl-Shift-K) to raise and lower a hand during a call. This is important for accessibility. Unfortunately the keyboard shortcut feature breaks, and remains broken for the rest of the call, if the user opens the chat window.

This, please fix this issue. Shortcut for mute (shift+ctrl+m) is still working, If you leave the meeting and rejoin, it works again (until you open the chat window again)
