It’s coming, it’s coming. I just pushed a modification to the fix, it’s tricky because the passkeys’ conditional UI is unevenly supported by browsers.
There is an API to check if the feature is supported, described here: PublicKeyCredential: isConditionalMediationAvailable() static method - Web APIs | MDN, but the call to isConditionalMediationAvailable() behaves differently on different browsers.
In Firefox. it is completely unsupported. In Safari on iOS, the feature is supported, but calling isConditionalMediationAvailable() returns false… so I had to modify the code to add a feature check just for Firefox.
Once tests pass, I will merge the change, it should be then available in about an hour.
