Implements the "top layer" concept from "CSS Positioned Layout Module Level 4" specification. - The tree builder is modified to ensure that layout nodes created by top layer elements are children of the viewport. - Implements missing steps in `showModal()` to add an element top top layer. - Implements missing steps in `close()` to remove an element from top layer. Further steps could be: - Add support for `::backdrop` pseudo-element. - Implement the "inert" concept from HTML spec to block hit-testing when element from top layer is displayed.
