+<p>All <a>document trees</a> have an associated <dfn>fullscreen element</dfn>. The

+<a>top layer</a> whose <a>fullscreen flag</a> is set, if any, and null otherwise.

+<p>To <dfn>fullscreen an <var>element</var></dfn> within a <a>document tree</a> whose root is
+<var>document</var>, set the <var>element</var>'s <a>fullscreen flag</a> and <a>add</a> it to
+<var>document</var>'s <a>top layer</a>. If the <var>element</var> is in a <a>shadow tree</a>,
+set <a>fullscreen flags</a> of all <a>shadow hosts</a> in its <a>shadow-including ancestors</a>.

That particular case doesn't actually work because `attachShadow({ mode: 'open' /* or 'closed' */ })` throws an exception, but yeah, the general question is what should happen you first fullscreen the shadow host and an element in its shadow tree, is that different from directly fullscreen the element in the shadow tree?
