r265273 changed this test to be promise-based. Now the missing 'update' event entry is present but the test times out waiting for the resize event.

Debugging shows an initial resize event being raised with the final video resolution (320x240), but before the update event on the sourceBuffer is raised to continue the test.

Subsequent calls to HTMLVideoElement::scheduleResizeEventIfSizeChanged happen with no size change, skipping the resize event.

This test is also crashing sometimes

On the runs for the last 4000 revisions (from r264991 to r268991) it
 crashed 8 times in the GTK release test bot
 crashed 18 times in the WPE debug test bot
 crashed 111 times in the GTK debug test bot

On the last crash for GTK debug (r268968) is hitting an assertion:
