According to WebKit results it was passing until:
238772@main

[Diego Pino]

r278821 (r238774@main) updated the baselines of this test for several platforms.

https://trac.webkit.org/changeset/278821/webkit

The changeset didn't cause a regression in GTK/WPE, since the number of failures for this test is the same as before. The GLIB baseline needs to be updated.

[Diego Pino]

I was wrong. What r278821 did was to remove the existing port baselines for several platforms, and now only the general and GLIB baseline remains.

So it was makes sense is to remove the GLIB baseline and add the failing test to GLIB TestExpectations, using this bug as bug number.
