Log Message:
-----------
[Site Isolation] fast/shadow-dom/shadow-at-root-during-disconnect.html fails
https://bugs.webkit.org/show_bug.cgi?id=313103
Reviewed by Megan Gardner.
The test called parent.pass() synchronously from the SVG script, immediately
after
appendChild(parent.target) moved the iframe between documents. The reconnected
iframe's
javascript: URL is executed asynchronously (queued as an event loop task by
PolicyChecker
because isInitialFrameSrcLoad is true), so with site isolation's additional IPC
overhead,
the test would finish before the second alert fired.
Fixed the test by adding 0s delay before calling pass so that the pending
javascript:
URL execution task time to fire first.
