WebKit ToT Screenshot - Passing

Reference screenshot from WebKit ToT - passing and matching other browsers.

NOTE - Minibrowser show 'Safari 16'.

Marking this as 'RESOLVED CONFIGURATION CHANGED', please triage and add related commit but this is passing on WebKit upstream and might in future Safari Technology Preview releases.
