Permissions aren't enforced correctly in the post editor, allowing under-10k users to view deleted posts whose IDs they know.
- Here is a deleted question of mine. This is only visible to 10k+ users.
- Here is the page to edit it. This should only be visible to 10k+ users, but is visible to everyone.
As much as it will disappoint me to lose this newfound ability, this should probably be fixed.
If this is the intended behaviour, then there is a related bug: I can't see my own deleted question. There's no way for me to vote to reopen it, as Jeff says in that post.
