            Bug ID: 228204
           Summary: [iOS] media/video-presentation-mode.html is a flaky
                    timeout
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: iPhone / iPad
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org

media/video-presentation-mode.html

Is a flaky timeout on iOS 14 E Simulator wk2.

History: https://results.webkit.org/?suite=layout-tests&test=media%2Fvideo-presentation-mode.html

There is a bug about a crash seen on Big Sur Debug wk2: https://bugs.webkit.org/show_bug.cgi?id=221414

I am creating a separate bug for iOS since iOS is timing out instead of crashing.

I see one crash at r277964 (Crash Log URL: https://build.webkit.org/results/Apple-iOS-14-Simulator-Debug-WK2-Tests/r277964%20(1329)/media/video-presentation-mode-stderr.txt) which shows a very similar crash log to one reported in https://bugs.webkit.org/show_bug.cgi?id=221414

I was not able to reproduce the timeout on my local machine using run-webkit-tests -f --debug --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --ios-simulator --iterations 50 media/video-presentation-mode.html
