STR: 1. open two tabs with input fields (e.g. two times https://bugzilla.mozilla.org/home) 2. hold a button (e.g. the key 1) switch to the other tab (with a left click from the mouse) and release the '1' key simultaneously. 3. retry (it took me ~10-15 tries) 4. see that on the other tab the key is entered endlessly and switching tabs from now on always inputs that key Pressing the '1' button or 'esc' stops inputting the 1. Found that while trying to find a reliable way to reproduce https://forums.mozillazine.org/viewtopic.php?t=537163 (scrolling through history instead of the page happens happens to me sometimes). Might be related.

Might be related, e.g. because of chaning tab while releasing the alt-key. Edit: I tried to reproduce again, but stopped trying after ~30 tries ^^. If necessary, I can create an rr log/screen recording.
