[inert] The modal dialog and the fullscreen element should escape inertness of ancestor

According to the spec:
https://html.spec.whatwg.org/#modal-dialogs-and-inert-subtrees

While document is so blocked, every node that is connected to
document, with the exception of the subject element and its flat tree
descendants, must become inert. subject can additionally become inert
via the inert attribute, but only if specified on subject itself
(i.e., subject escapes inertness of ancestors); subject's flat tree
descendants can become inert in a similar fashion.

The modal dialog should escape the inertness set by an ancestor
with the inert attribute. Consider this test case:
\<div inert>
\<dialog>find me!\</dialog>
\</div>
\<script>document.querySelector("dialog").showModal()\</script>

The return value of window.find('me') should be true,
because \<dialog> does not specify the inert attribute.
