Description

[Alastor Wu [:alwu]]

In test_trackelementevent.html, we set a resource bad.vtt to the track element [1]. However, we didn't have that file in our codebase.

From the history [2], I even didn't find that file in the first changeset. We should create an actual file, instead of assigning an invalid address.
