Summary Whole DOM tree can leak if Document is hover/active/focus node on quit

DocumentImpl keeps the hover, active and focus nodes referenced, so the whole DOM tree can leak if the document itself is hover, active or focus when leaving the page. Without this fix, the editing layout tests show 175 NodeImpl leaks with the counter enabled.

Created attachment 5966 [details] patch to fix the leak when document is hover/active/focus node I'm not sure if this is the best approach. Maybe it should be FrameView, not Document, that tracks these nodes.

Comment on attachment 5966 [details] patch to fix the leak when document is hover/active/focus node r=me, although the hover/active node should never be the document.

The hover/active node becomes the document because detaching a node makes it walk up the parent chain until it finds a node with a renderer, which the document itself still does when first detaching.

Mass moving XML DOM bugs to the "DOM" Component.
