Bug 244107 – [WebAuthn] Conditional UI for webauthn autocomplete breaks with multiple input text fields

• Status: RESOLVED
• Resolution: MOVED
• Component: Forms

On the latest nightly build of Webkit on macOS 13 beta 5 the conditional UI (https://github.com/w3c/webauthn/wiki/Explainer:-WebAuthn-Conditional-UI) functionality for Passkeys only works as long as there is only one <input> text field on the page.

Reproducing Steps:
1. Webpage with <input autocomplete="webauthn" >
2. Perform webauthn get with a conditional mediation:
navigator.credentials.get({
  mediation: 'conditional',
  publicKey: {
    challenge: <challengeFromServer>,
  }
});
3. Click into the input box - note that the conditional UI appears
4. Add a second <input type="text"> field to the page (with or without the autocomplete tag). 
5. Perform same webauthn get - the conditional UI autocomplete does not appear.

The cause of this bug was outside of WebKit code, so resolving as MOVED.

We believe this is fixed in iOS 16.4.1 and macOS 13.3.1.
