Passkeys and multiple accounts for a site is broken

Since the release of https://releases.1password.com/b5x/beta/#1password-in-the-browser-2.14.2 I can now sign in with passkeys for multiple Google accounts.

Interestingly, when I sign in on https://accounts.google.com/ 1Password shows a list of all possible items that has a passkey, and it's just a matter of choosing the right one. However, on https://passage.1password.com/demo, 1Password only shows one item (and it's the correct one) even though I have multiple items with passkeys for that site, so that site certainly works better in that regard, as there's no risk of choosing the wrong account. The demo site still isn't fully functional though, as 1Password doesn't show it's inline menu in the Email or phone number field and clicking in Autofill in the extension doesn't do anything. You have to drag and drop or copy/paste, which isn't ideal for a demo site.

I created https://1password.community/discussion/140586/feedback-regarding-the-1password-passkey-demo-site#latest a while ago but I never received any feedback from 1Password there and Passage never got back to me after their first email reply, so I thought I'd just mention this here instead.
