Bug 1705132 [wpt PR 28478] - content-visibility: Ensure to dirty continuations on force unlocks., a=testonly

Automatic update from web-platform-tests content-visibility: Ensure to dirty continuations on force unlocks. This patch ensures that we propagate a dirty bit from the continuations up the ancestor chain when we do a force unlock. In "regular" cases where we don't need to force unlock anything, we have layout containment which should prevent us from having continuations.
