Attachment: Bug 1490791 - Make ShadowRoot stylesheet list work only when the shadow root is connected.

This avoids the issue of triggering stylesheet loads for disconnected stuff and
such, and is more consistent with Chrome and WebKit.

This is per the recent CSSWG resolution at
https://github.com/w3c/csswg-drafts/issues/3096.
