The navigation "page link" feature gives you the option to create a page as a draft, but its search does not resolve drafts.

If it can create drafts and add them to the menu, then it should be able to search drafts and add them to the menu.

One problematic example could be if a user adds a navigation block, links a page by creating a draft option, and is then interrupted (the nav block errors and must be removed / re-added, the editor errors and must be reloaded, the nav block is accidently deleted, etc.). Now the user must re-add the navigation block, page link will not find the newly created draft and force the user to create ANOTHER draft for the same page - this will result in duplicated draft posts and confusion down the road.

What I would expect

For drafts to show up in the results of the page search.
