Re: [w3c/uievents] Standardize layerX/layerY on MouseEvent (#135)

We should do this, lack of interop here is a bit unfortunate.

Rather than depending on arbitrary layerization by the browser (which is, AIUI, what's going on in Blink and WebKit), we should come up with a more reasonable / interoperable definition...

In Gecko, we use the closest abspos containing block or scrolling box (and per https://github.com/webcompat/web-bugs/issues/94500 we should add outer `<svg>` as well I guess).

@christr @mfreed7 @smfr would such a definition work for Blink / WebKit? That should be a reasonably-interoperable definition.

It hasn't brought any other compat issues other than the one mentioned above to my knowledge, (which WebKit also suffers from), and the proposal of including outer SVG would fix.
