Passkey autofill (aka conditional mediation)

Does conditional mediation (essentially "autofill of passkeys") work in the current beta release?

I'm unable to get it working across multiple web apps that othewise support it (using Chrome or Safari's native Passkey support). An example you can try for yourself is this Passkey demo website (it's an example, so you can create an account with any fake user/pass combo):

• https://webauthn-conditional-ui-demo.glitch.me/

Specifically what we see is:

• Adding a passkey to a 1Password entry in a vault works correctly
• Regular passkey login with 1Password works correctly (see first screenshot below)
• Conditional mediation doesn't - what seems to happen in all sites we tested is the passkey shows up to select, but only the username is filled in (see last 2 screenshots below)

To try regular passkey login use the "Vanilla Webauthn" button - which works correctly:

But, if you try to use the passkey autofill (conditional mediation):

Thanks.
