[Bug] KC_GESC does not play nicely with Firefox

Describe the Bug

Trying to type backtick in in Firefox using KC_GESC does not work as intended. No backticks are inserted. Likely because if KC_GESC appears in the keymap, then the Super key is changed to only send its corresponding keycode on KeyUp. Now, when pressing Super+Esc, the backtick keycode is actually detected, but the text character is not inserted. Waiting for keyboard repeat to first kick in, then releasing Super while still holding Esc, allows for backticks to actually be inserted. A workaround I found is to map Fn+Esc to KC_GRV.

I understand this is not entirely a QMK-only bug, but I wanted to ask here to see if there are any other workarounds, or if anyone else has run into this issue before.
