Reviewed by Per Arne Vollan and Alex Christensen.
In the site-isolated case, WebKit suspends pages with
Messages::WebPage::SuspendWithFrameItem
instead of Messages::WebPage::SetIsSuspended. The SetIsSuspended handler calls
WebPage::suspendForProcessSwap()
which breaks the opener link via frame->detachFromAllOpenedFrames() when the
opener's page is put into the
back/forward cache during a COOP-triggered process swap. We should do the
equivalent in WebPage::suspendWithFrameItem().
