repro of #id::slotted not working

Prefixing `::slotted()` with an #id selector does apply the styling.

Repro: http://jsbin.com/qetofazevu/edit?html,output


      #s::slotted(*) {
        background: red;
    <slot id="s"></slot>

    var t = document.querySelector('template');
    var nav = document.querySelector('nav');

- using `::slotted(*)` and `slot::slotted(*)` does apply the styling.
- repro works in Chrome 53+

It looks like replacing #s::slotted(*) by .s::slotted(*) and adding class="s" to the slot element fixes the problem.  So there's something about the style selector or collector that doesn't like using #s and ::slotted together.
