• Component: New Bugs

http/tests/misc/iframe-shadow-realm.html 
 
Is a constant timeout on iOS16 and macOS wk2 ToT and since 254483@main. It appears that it was expected to fail after 254483@main. However, it wasn't expected to timeout judging by the expectations set.

This issue can be bisected to 254483@main using command:

This is probably just fall out for disabling ShadowRealm.  All we need to do for this test is add this at the top of the file:

<!-- webkit-test-runner [ jscOptions=--useShadowRealm=true ] -->

Yusuke tells me that this test as currently written can timeout.  So, this is expected behavior.

FYI, skipping the test is the right thing to do here (which Hercules just landed a patch for) because a test expectation of [Pass Fail Timeout] gives us no information, and wastes EWS time with time outs.
