REGRESSION(r199017): [GTK] Layout test media/media-source/media-source-sequence-timestamps.html is failing

[Michael Catanzaro]

Layout test media/media-source/media-source-sequence-timestamps.html is failing since r199017 "Regression(r196145): Crash in getOwnPropertyDescriptor on ​http://www.history.com/shows/vikings"

That commit looks completely unrelated to media-source, but our layout test bot does not lie, the test is not flaky at all and is is blamed to either 199016 (which is definitely not it) or r199017. Huh. Text diff:

Updating expectations accordingly.

Note this looks really similar to bug #163516, but these are regressions from different commits.
