Interesting. I sometimes get similar behaviour on KDE / wayland, usually it is "2" or "3", and it seems to only affect electron apps. Always thought it has something to do with a dodgy ps/2 to usb converter I use to attach my old mechanical keyboards. I think it does not happen if electron apps are started with "--ozone-platform=wayland" but not completely sure, and I have no reliable way to reproduce or somehow trigger that behaviour.
