Fix crash in WebFrameProxy::didCreateSubframe with site isolation on
https://bugs.webkit.org/show_bug.cgi?id=294498
Reviewed by Charlie Wolfe.
Site isolation introduces a race condition that has caused several crashes for
me today.
If a frame navigates from one site to another and when the frame load commits
in the next
process, the previous process creates a new iframe, we can hit this assertion.
When this
condition is hit, it is correct to ignore the message from the previous process
and do nothing.
