…s-001.html

This CL is a follow-up CL of crrev.com/c/2134466. This TC has an
issue number[1] that introduced it. But, since Chromium changed
the behavior at [2], it should be updated with the latter. It also
updates "assert" to deliver clear messages.

[css-filters] Migrate feimage-reference-foreign-object-crash.html to WPT

This test moves feimage-reference-foreign-object-crash.html to wpt/.

It also migrates the test into a regular crash test that waits long
enough to check that the crash does not really happen using
class="test-wait" (hence dropping the use of testharness.js
and testharnessreport.js).

Differently from [1], circular reference isn't used.
