- allow running with multiple workers (tested with up to four workers locally which
didn't show signs of flakiness)
- prevent race condition with webauthn tests (running them in parallel
on the same user could prevent another test from logging in)
- fix flakiness on CI action status (Chromium sometimes needs a long
time to fill the href field, firefox is always faster)
