Could you attach a screenshot of what you're seeing?

(I don't think I see it.)

This is really weird.... jwatt, do you have time to look into this?

This happens in older Firefox versions (32, 33) as well, so not an obvious recent regression.

It might be interesting to see if the bug is also present if a scale is used.

It almost seems like there's a call to PreservesAxisAlignedRectangles() that meant to be a call to HasNonAxisAlignedTransform().
