[css-pseudo-4] outline on ::selection

[fantasai]

We had listed 'outline' as supported on ::selection, so I tried my best to add a reasonable definition of what that would mean:

The outline, if supported, must be drawn around the union of the active portions of the highlight overlay precisely along the boundaries of those portions and not between congruent parts. The UA may use the outline styling of the nearest common ancestor of any continuous or discontinuous range rather than piecing together varying styles of outline into a single shape.

It seems a bit crazy, so I'm wondering if it should be dropped from the list of supported styles or any implementer thinks it's worth keeping.

I'm in favour of removing it.

<jensimmons> Thanks for letting me announce that! Thanks astearns !
<dael> fantasai: currently outline applies. I tried to add a definition but it's not that simple and I don't think anyone impl. Does anyone want this? If not we can drop it. It's able selection as well as spell check.
