[Beta 17] Keyboard Shortcut for Start/Stop Speaking Unavailable in Composition Mode

I have set up a custom keyboard shortcut for Start/Stop Speaking, but it does not work in full-screen mode. I’ve tried various available combinations (some combinations don’t work in editor either).

Other Custom Keyboard Shortcuts Unavailable in Composition Mode:
ALT + any letter = sometimes only types that letter

Other Custom Keyboard Shortcuts Unavailable in Any Mode:
ALT + tilde = sometimes types the ~, sometimes does nothing

(let me know if I need to make a separate post for these last two)

I can confirm that the same happens to me in composition mode.

Thanks,
Miik
