The !m_shouldReuseMainFrame removal in ProvisionalPageProxy and the coreLocalFrame() change in WebFrame::commitProvisionalFrame are not needed. The CommitTiming::Immediately fix handles the about:blank case on its own: the second takeWindowProxyAndOpenerFrom in commitProvisionalFrame transfers the WindowProxy from remoteFrame to localFrame unconditionally, and when the frame ID is non-null it is always a different frame, so the original coreFrame() code was already correct. 2217310 1 webkit-bug-importer 2026-06-03 12:13:56 -0700 <rdar://problem/178649065> 2217316 2 roberto_rodriguez2 2026-06-03 12:17:04 -0700 Pull request: https://github.com/WebKit/WebKit/pull/66394 2217437 3 ews-feeder 2026-06-03 18:06:30 -0700 Committed 314515@main (d176a27fbd87): <https://commits.webkit.org/314515@main> Reviewed commits have been landed.
