Does this mean that the pointer-events values other than normal|none
also have no effect, and elementsFromPoint always pretends the value
is "auto"?  This only applies to SVG elements, but still.

I can see the point of that, but I can also see it being useful for it
to match elements that you'd actually hit-test against.  Maybe a flag?
