Automatic update from web-platform-tests Fix flaky wpt longtask-timing tests - Remove restriction of a single entry for events due to noise/unknown entries in the longtasks API - Provide a timeout mechanism that will allow the test to fail cleanly if the entry is not received after a certain period of time.
