John Schanck ced65429f4 Bug 1877790 - give new webauthn requests priority over pending requests. r=keeler
Previously, a new webauthn request would only have priority over a pending
request if there had been a visibility change. This was an arbitrary design
decision, and was inconsequential before conditional mediation was implemented.
