Reference Screenshot (of Safari 15.6)

Hi Team,

I am going through Chrome Bugs and noticed following test case, which is broken in Safari 15.6 on macOS 12.5 and it does not show any boxes etc.

Test Case Link - https://jsfiddle.net/brc580sz/show

Chrome Bug - https://bugs.chromium.org/p/chromium/issues/detail?id=1314583

*** STEPS TO REPRODUCE ***

1) Open JSFiddle and run

>> EXPECTED RESULT:

It should show the outlines etc.

>> ACTUAL RESULT:

Safari does not show outlines etc. like other browsers (Chrome Canary 106 & Firefox Nightly 105)

____

Please refer to attached screenshot as reference and also if it is fixed in upstream Webkit Nightly then please ignore and mark it as Duplicate.

Thanks

This is failing because OffscreenCanvas isn't supported yet, and the 'transferControlToOffscreen' call is erroring.
