When navigating back, the suspended page and its iframe processes are unsuspended, the WebCore BackForwardCache entries are restored, and the frame tree (including RemoteFrames) is reconstructed. The browsing context group is swapped back onto the page, preserving existing RemotePageProxy objects. 2203317 1 basuke 2026-04-22 14:13:32 -0700 <rdar://problem/173743733> 2203318 2 basuke 2026-04-22 14:13:48 -0700 Pull request: https://github.com/WebKit/WebKit/pull/63355 2209995 3 ews-feeder 2026-05-11 22:06:40 -0700 Committed 313059@main (fceeb850c1e2): <https://commits.webkit.org/313059@main> Reviewed commits have been landed.
