@tbsbdr @kulmann did we target Firefox as supported browser in the audit? Can confirm this is only an issue in FF and not in Chrome

This one is very tricky! Would it be an option to replace it with an out-of-the-box accessible date picker? Could take the same amount of time like fixing this, but will cause no (or at least less) problems in the future:
