Log Message:
-----------
REGRESSION(302408@main?): [iOS Release ]
http/tests/site-isolation/history/add-iframes-and-navigate-mainframe.html is a
flaky crash
https://bugs.webkit.org/show_bug.cgi?id=302486
rdar://164649768
Initially, we added this MESSAGE_CHECK at the start of commitLayerTree() to
verify that main frame data is only provided
from the main frame process. However due to some race conditions that occur
with cross site navigations in
SI, some tests like
http/tests/site-isolation/history/add-iframes-and-navigate-mainframe.html,
TestWebKitAPI.SiteIsolation.NavigationAfterWindowOpen, and
http/tests/site-isolation/window-open-with-name-cross-site.html
are flaky crashes now. We revert the MESSAGE_CHECK for now. The follow up fix
is being tracked in rdar://164916965.
Unreviewed, reverting part of 302408@main.
