Description Boris Zbarsky 2016-04-29 21:17:43 UTC 
clientWidth/Height return the viewport dimensions, whereas clientLeft/Top return the border width of the root element.  The combination of these behaviors is not very helpful: the different client* measurements are referring to totally different rectangles.

I think clientLeft/Top should return 0 in exactly the cases when clientWidth/Height map to viewport dimensions.
