History: 
On 281435@main WPT import occurred and the test has been failing since. Although, the test itself was not touch. Investigating further.

REPRODUCIBILITY: 

It seems that there is a test leakage occurring, since I was not able to reproduce the regression running the test in isolation. 

I was able to reproduce the regression on ToT if this test 

imported/w3c/web-platform-tests/css/css-fonts/font-face-unicode-range-nbsp.html

imported/w3c/web-platform-tests/css/css-fonts/format-specifiers-variations.html 

is within the same test run. 

Ive attached the test list. 

The command, 
$ run-webkit-tests --test-list test_list.txt --child-processes=1 --exit-after-n-failures=1

Created attachment 472065 [details]
Test list used for reproduction

Should not set test expectations since the test failure may go to anther test. Still investigating.

Thank you for looking into this Anfernee; I'm was about to file it but noticed you had.

imported/w3c/web-platform-tests/html/canvas/element/text/2d.text.draw.fontface.notinpage.html is also the same way from this exact point.

With the above commit, resolution was to re-baseline.
