clip-path breaks pixelated canvas rendering

Project Member Reported by jakearchibald@chromium.org, May 16 2018 
https://pixelated-transform-demo.glitch.me/

These are all canvases & imgs displayed at 10x using different methods, all with pixelated image-rendering. Some have a null clip-path applied. The output of each should look the same.

In the cases where clip-path is applied to a canvas (or a parent element) the pixelated rendering fails, and it falls back to interpolation.

This only happens for canvases > 256px in size, which I believe triggers some kind of hardware rendering path.

Version 68.0.3431.0 (Official Build) canary (64-bit) OSX

Of which the most likely candidate is

Not sure why, however.

Ah, didn't realise this was a regression. Sorry for not bisecting myself.
