This needs to change with site isolation because a navigating iframe may have parent frames that are out-of-process, for which we cannot synchronously create history state. Instead, when a frame navigates, the web process should only create and commit history state for the navigating frame and its children. If the navigating frame is a child frame, we can use the current item in the UI process's back/forward list to populate the history state for its parent frames. 2084175 1 webkit-bug-importer 2024-12-28 18:33:47 -0800 <rdar://problem/142134339> 2084176 2 charliew 2024-12-28 18:37:38 -0800 Pull request: https://github.com/WebKit/WebKit/pull/38410 2084742 3 ews-feeder 2025-01-03 10:38:23 -0800 Committed 288409@main (9b13b53b41a1): <https://commits.webkit.org/288409@main> Reviewed commits have been landed.
