Red is visible on rendered page.
Note that this test CRASHES on EFL Debug.

Setting a depend flag on bug #88311 - the bug will only cover fixing the crashing, the red output is still visible (though not as much).
Also note that this test was updated upstream to use the 'vmin' type instead of 'vm'. 'vm' is not supported at all by WebKit and using 'vmin' reduces the amount of red output, but I'm not sure whether to change the type manually or wait for an update to the whole testset.
Almost fixed in bug #86176. Will set a depend flag on that, with #88311 resolved as a duplicate of that.
