"elements" includes the full-features pseudo-elements (::before and
::after) unless otherwise specified.

However, I know that at least Chrome implements resizing by applying
width/height properties directly in the style='' attribute on the
element, which pseudo-elements obviously don't have.  That's probably
what's happening in Gecko too, it just walks up to the generating
element to find something with a style='' attribute.
