> The values of window.innerWidth and window.innerHeight seem to return CSS pixels multiplied with the page scale. I have not found an authoritative reference on whether these values should include page scale or not, but seeing as 1) the effects of text zoom is already cancelled out and 2) providing scaled CSS pixel values to web developers does not seem useful, I believe the page scale should not be included.

I am wondering whether this change we made makes sense as it seems be differ from most widespread mobile implementations.

"Dimensions of the visual viewport in CSS pixels."

This is also what current OS X Safari supports.
