Invoke the drawImage() API with a video element fails on Fennec Nightly, m-c. It works on Fennec Beta and desktop all channels. Here is a sample page: https://people-mozilla.org/~tkuo/test/test_drawImage/test_drawImage.html You can see the exception message at the console. This failure forbids some media mochitests.

Tzuhao, is it possible for you to use mozregression to figure out which change regressed this?

Tzuhao, what device are you using? I could not reproduce on today's nightly on my phone (Google Pixel). So perhaps this has been fixed again, or is device dependent.

My mistake, this is reproducable. Looking in to it.

I can still reporoduce it on the latest Nightly on Google Pixel, Nexus 5, Nexus 6 and Samsung S8+.
