Comment 3

[Jamie Nicol [:jnicol] out of office until 6th Jan]

These tests were marked as fails-if(geckoview&&!webrender). They are failing on geckoview because of bug 1558513: there is an offset between the emojis in test and reference images.

The reason that they were passing on webrender previously was because the emojis weren't being drawn at all, so both the test and reference images were blank. Bug 1562316 fixed the emojis being drawn with webrender, but bug 1558513 remains (they are still offset).

So I will update the test annotation to simply fails-if(geckoview).
