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](https://developer.mozilla.org/en-US/docs/Web/API/PublicKeyCredential/isConditionalMediationAvailable), 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.
