He is right. According to the spec:
"The clearRect(x, y, w, h) method must run the following steps:
3. Clear regions that cover the pixels in pixels on the scratch bitmap."
Does this need a testcase? I'm lacking context as to whether these are new features or bugs.

This would be a bug, but we need an STR here if at all possible.
