F37 on tablet, on-screen-keyboard does not type (observed in Thunderbird)

Problem

The on screen keyboard is stuck in “suggest a word” mode (lists words above keys), and does not type to screen. AFAIK only “Enter” and “backspace” are relayed.
Issue first discovered in Thunderbird on a Dell Tablet (WACOM Touchscreen).
Freshly installed F37 Workstation.

Cause

Start Thunderbird,
“write” new message,
tap the “message text area” → the on-screen-keyboard does not appear,
pull up OSK (gesture: swipe from bottom up),
focus on “message text area” lost → tap again,
start typing.
Either no output appears, or suggestions are highlighted on OSK.
It looks like every key-touch is immediately backspaced.

Related Issues

Once issue is triggered, other applications are potentially affected (launched Firefox and Chromium and saw same behaviour)

Workarounds

Reboot (or change tablet orientation to rotate screen once)

Hi, please file a bug against gnome-shell and link it here, thanks.

Raised issue on Gnome-shell gitlab and added screencast.

I have removed “Typing Booster” to prevent typing suggestions to be displayed in the first place.
Therefore I have worked-around the issue.

The osk has been usable since removal of “Typing Booster”.
