            Bug ID: 229268
           Summary: [GTK] Test media/media-fragments/TC0009.html is flaky
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: clopez at igalia.com
                CC: bugs-noreply at webkitgtk.org

The test media/media-fragments/TC0009.html is flaky on GTK (but not on WPE).

The flakiness can be easily reproduce with:

$ Tools/Scripts/run-webkit-tests --repeat-each=100 --debug-rwt-logging --release --gtk media/media-fragments/TC0009.html


When it fails this is the diff:

 Comment: The request lies beyond the end of the resource. If the UA knows the duration of the resource, it seeks to the end of the media resource. Otherwise, the UA will send an (out-of-range) HTTP request with an 'include-setup' in order to setup its decoding pipeline.
