Posts in the Trash drag attachment pages down with them

[markel]

If you have an attachment linked to a post, then move the post to the Trash, the attachment page results in a 404.

Steps to reproduce:

1. Create a new post with at least one image attached to it (just add it to the post).
2. Publish the post.
3. Check both the attachment URL (it will be a "child" of the post to which it is attached) and the post URL.
4. Move the post to the Trash.
5. Try to "View" the attachment either by going through the Media Library or by refreshing the attachment URL. WordPress will display a 404 message.

Deleting the post permanently can cause the attachment permalink to work again, both with the page parent in the slug and without that information in the form  http://sitename.com/attachmentname/ .

Attachments inherit post status from the post they are attached too so they should behave as if they were no longer published which is what is happening here.

Why would you expect otherwise?

Point taken.

I'll argue then instead that the permalink should also result in a 404 when the post has been permanently deleted.
