Comment (by dd32):

 @nacin might be able to give some input here, as #14122 implemented a lot
 of the logic around this.

 As far as I can see, it's a developer error to not set `delete_posts` in
 the capabilities array, and leave `map_meta_cap` as false.

 The more I look at it, the more the patch seems correct, even though we
 shouldn't need to. The other option is that using `delete_posts` in that
 context could be seen as wrong to start with.
