Description Simon Fraser (smfr) 2023-11-01 16:21:58 PDT

In EWS it's common to see crashes in tests that run after platform/ios/mediastream/video-muted-in-background-tab.html (these are often scrollbar tests).

platform/ios/mediastream/video-muted-in-background-tab.html calls window.internals.setPageVisibility(false); which seems to trigger this. When running locally, this test actually triggers a SpringBoard crash, and then some subsequent test asserts in -[WebKitTestRunnerApp applicationDidEnterBackground:].
