Kaku, any idea what might be going on here?
I am out of office from 9/26 to 10/11 and I will try to check it once I have free time.
So, I am back and I looked into this problem today with only few observations. I cannot reproduce it locally and I still have no idea about the root course, however, I found that this bug seems to be related to bug#1209317. Seems that something wrong within the Canvas/CanvasRenderingContext I used to create an ImageBitmap. Keep working.

See log for mochitest chunk 14 > https://treeherder.mozilla.org/#/jobs?repo=b2g- > inbound&revision=048b60ee7fdd&exclusion_profile=false&selectedJob=3719204 After the second glance over the log, I realized bug 1238463 is instead the right bug. Sorry for the noise.
