Re: UA's implementation of ::selection

Why do you want to create a pseudo element for each
element of the DOM? It would be sufficient to use a
::selection object for the root element. Or at least only
one for each element of the DOM needing a special
styling. It's not needed to create a new instance of
the selection styling object for each element of the
DOM. They can share the same.

Or is that impossible ?
