This resolves#7044 which involved callbacks
in a queue not receiving the same timestamp despite

Implement Element.client{Top,Left,Width,Height}
This isn't done, but contains a working implementation of at least `clientTop`. Feedback would be much appreciated: it's probably far from ideal.
Implementing `clientLeft` is straight-forward, I think, but `clientWidth` and `clientHeight` require accessing the `border_box` - and I don't know how that works, yet.

This fixes a bug with elements with multiple class attributes. In this case,
the class attribute in the null namespace would only be considered if it was
the first class attribute in the list.
