Shift keys don't work in Wayland on Ubuntu

When I start Firefox on Ubuntu under Wayland, Firefox behaves as if both shift keys just stopped working. In any text field pressing either Shift and any character inputs nothing, e.g. Shift+A inputs nothing instead of "A".

This only happens in Firefox, not in any other app that I checked (terminal, Chrome). It also doesn't happen if I start Firefox in a Xorg session.

Pasting such characters *does* work, e.g. I can paste "about:support" in the URL bar but not type it (":" requires shift).

This also happens when I start Firefox in troubleshooting mode.

What are the next steps in troubleshooting this?

Additional troubleshooting info - I verified that MouseEvent: shiftKey property does respect the Shift pressed, i.e. I can get "The shift key is pressed: true" in this demo: https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/shiftKey

So it seems only text input fields are affected by this.
