The bot wpe-arm64-release completed 1023 runs on the interval [308164@main-310858@main]
Frequency of results for test: media/playlist-inherits-user-gesture.html
  976 times [95.4%]      ->  NOERROR
  43 times [4.2%]        ->  TIMEOUT PASS
  4 times [0.4%]         ->  TIMEOUT

Of those 1023 runs it didn't match the expectation 47 times [4.6%]
Details of the type and frequency of unmatched expectations:
  43 times [4.2%]        ->  TIMEOUT PASS (Expected: PASS)
  4 times [0.4%]         ->  TIMEOUT (Expected: PASS)

Flakiness factor: 8.9%
    - This test was flaky on 8.9% of the 1023 runs analyzed, either giving different
      results within a single run, or a different result than in the previous run.

This test is also a flaky timeout on WPE x86_64:

https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=media%2Fplaylist-inherits-user-gesture.html&platform=GTK&platform=WPE

(for instance in revision 310984@main: https://results.webkit.org/urls/build?platform=WPE&version=2.53.0&is_simulator=False&style=release&flavor=wk2&architecture=x86_64&suite=layout-tests&uuid=177588699900&after_time=1775889047&before_time=1775889047

The test is also a flaky failure on WebKitGTK:

https://build.webkit.org/results/GTK-Linux-64-bit-Release-Tests/310941@main%20(24497)/results.html

The stderr is:

```

There are many media tests that are also "timeout pass" failing with a similar stderr. Those tests are filed under bug webkit.org/b/309438. Closing this bug in favor of the latter.
