Image Diffs for bug.

Image Diffs seem to indicate that Airplay is being initiated with the tests, and are throwing off the diffs

[Robert Jenner]

I was able to reproduce the failure on macOS Sequoia Release ToT running the test as follows:

run-webkit-tests media/media-source/media-managedmse-video-with-poster.html --iterations 1000

In the 1000 iterations run, it produced an ImageOnlyFailure 18 times.
