bug(linux): Gnome + Firefox + Keyman instant log out of session on backspace in HTML input field (Wayland)

Backspace in HTML input fields (like a Google search field) cause Gnome session to instantly crash, returning user to login screen.
This did not happen in previous LTS.

Backspace removes characters from string, session continues without crashing.

### Related issues

Slightly different issues on 2 identically set up machines. One also has a problem with copy/paste in LibreOffice Writer where ctrl+x removes text, but inserts an x in its place. Ctrl+v does not paste clipboard - letter v is inserted instead.
