            Bug ID: 173422
           Summary: [WPE] Some fast/animation/ tests crash irregularly
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit WPE
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: csaavedra at igalia.com
                CC: bugs-noreply at webkitgtk.org

These tests are crashing irregularly when ran with many iterations.

fast/animation/request-animation-frame-cancel.html failed unexpectedly (WebProcess crashed [pid=28834])
fast/animation/request-animation-frame-detach-element.html failed unexpectedly (WebProcess crashed [pid=28880])
fast/animation/request-animation-frame-disabled.html failed unexpectedly (WebProcess crashed [pid=28927])
fast/animation/request-animation-frame-disabled.html failed unexpectedly (WebProcess crashed [pid=28988])
fast/animation/request-animation-frame-during-modal.html failed unexpectedly (WebProcess crashed [pid=29030])
fast/animation/animation-style-update-size.html failed unexpectedly (WebProcess crashed [pid=29637])

The stacktraces are all pretty much the same and the problem is an assertion:
