The test PR didn't merge in WPT because of a lint failure:

ERROR:lint:css/css-will-change/will-change-abspos-cb-dynamic-001.html: Reference test with a non-existent 'match' relationship reference: 'will-change-abspos-cb-001-ref.html' (NON-EXISTENT-REF)

Yeah, by the time the lint ran the changes from bug 1498873 (which introduced that file) were in mozilla-central but not in wpt yet.

I restarted the Travis build which should make it pick up the right thing hopefully.
