Suspecting: r430954 from Narrow bisect

@xidachen  : Could you please help to reassign if your change is not the cause for this change.
Two things:

1. I tried locally on a a win7 and win10 desktop, and I cannot repro the same issue. Could you try different computers and see if that's consistent or not?

2. My change there is applied to ImageBitmapRenderingContext, and as far as I know, it is not used in printing.

OK, since ImageBitmapRenderingContext isn't used in printing, my change won't make such an impact. 

Add some more people to CC list, who were making graphics / Image related changes in the bisect result.

sadrul@, fsamuel@, halcanary@, please take a look. Thank you.

I am afraid I have no idea what the bug is (the videos look the same?)

I think the bug is supposed to be that the previewed page shifts slightly horizontally when it loads. Tried a few times on Canary (61.0.3141.0) on Win 10, and cannot seem to reproduce, but perhaps it is happening so quickly I cannot see it. Can anyone else reproduce this on 61?

Reducing priority since this is barely perceptible and does not seem to affect anything else in print preview.
