This test has been failing for a long time, but it was filed under an unrelated bug (https://bugs.webkit.org/show_bug.cgi?id=171726):

Opening this video ('LayoutTests/media/media-source/content/test-fragmented.mp4') in different browsers, returns a different length.

For instance, opening this video in Google Chrome and inspecting `video.duration` using developer tools returns a length of 10 seconds. However, doing the same on Firefox returns a video length of 10.049 seconds (same length as WebKit).

So I think the test should be changed and use a '>=' operator (instead of '==') to compare the video length. This is what other similar tests do, for instance: LayoutTests/media/encrypted-media/encrypted-media-append-clear-encrypted.html.
