Comment (by brettshumaker):

 I just ran into this inconsistency for a plugin I have that's doing some
 things in the admin bar. Originally it was only pulling a list of pages
 and adding their edit links to an admin bar item, but I had a feature
 request for the ability to add other post types to this item. I was doing
 so with `WP_Query` but found that it was breaking the edit screen in that
 the editable content was being pulled from the last post in my list of
 items in the admin bar. I thought that `wp_reset_postdata()` wasn't
 functioning properly at first but then realized what was going on.

 I agree with @boonebgorges and @misternifty that this does need to be
 fixed so that the main query behavior is consistent across the admin area.
 It doesn't make sense for `WP_Query` to work on some but not all pages.
