Bug 176959 – Layout Test imported/w3c/web-platform-tests/media-source/mediasource-redundant-seek.html is flaky

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Matt Lewis]

imported/w3c/web-platform-tests/media-source/mediasource-redundant-seek.html is a flaky failure on macOS El Capitan Debug WK2 according to the flakiness Dashboard:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=imported%2Fw3c%2Fweb-platform-tests%2Fmedia-source%2Fmediasource-redundant-seek.html

There isn't a clear regression point for the test on the board.

This test is not in Mac TestExpectations anymore and I can't see any recent failure in https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fmedia-source%2Fmediasource-redundant-seek.html

Closing this issue... but then opening a new one because we do have a flake in the GStreamer port in this same test.
