`clientWidth`, `clientHeight`, `getBoundingClientRects` all return `0` when querying elements within the shadow-dom.

EXAMPLE

Blocks: 1025945
For the clientWidth case, Element::GetClientAreaRect calls Element::GetScrollFrame which calls Element::GetPrimaryFrame which does:

1746   nsIDocument* doc = GetCurrentDoc();
1747   if (!doc) {
1748     return nullptr;
1749   }

which of course fails for shadow DOM things.  Do we have a bug tracking that yet?
Would this bug also apply to projected contents?
It shouldn't, no.
