Navigables are re-used for navigations within the same tab. Its current ownership of the cursor position is a bit ad-hoc, so nothing in the spec indicates when to reset the cursor, nor do we manually do so. So when a cursor update happens on one page, that cursor is retained on the next page. Instead, let's have the document own the cursor. Each navigation results in a new document, thus we don't need to worry about resetting cursors. This also makes many of the callsites feel nicer. We were previously often going from the node, to the document, to the navigable, to the cursor. This patch removes the navigable hop.
