Transition Group example on site fails in Safari

[IanBellomy]

(Apologies if I'm reporting this in the wrong place.)

What is the current behavior?

In Safari (desktop at least), in the transition group example found here, nothing happens when 'Add Item' is clicked.

What is the expected behavior?

A browser prompt modal appears.

Could you provide a CodeSandbox demo reproducing the bug?

@IanBellomy I couldn't reproduce it. Does this issue still happen on your Safari?

[IanBellomy]

Hrm. Yes. Safari 15.0 FWIW.

Looking for more details in Safari release notes, but looks like Salesforce has a known issue entry related to Safari 15 now blocking cross-origin dialogs (including 'prompt'):

I'm using Safari 15.3 and it's working correctly.

[IanBellomy]

Huh. In 15 and 15.4 (TP) I'm getting a very explicit error in the console.

Hmm, I couldn't reproduce it with Safari TP(15.4).
