https://chromium-review.googlesource.com/c/chromium/src/+/650248 removed several web-platform-tests files from the list of tests we skip.

https://chromium-review.googlesource.com/c/chromium/src/+/650028 is the first CL to automatically import them into Blink. One of the tests, external/wpt/html/semantics/embedded-content/media-elements/video_loop_base.html, crashes on a DCHECK and prevent further imports.

This crashes on Mac and Linux, and I think it'll fail on Windows as well (the tests are still running there).

For now, I'm going to mark this test as crashing so further WPT imports can continue.
