Comment (by peterwilsoncc):

 As the `$post_type` is defined only where the `WHERE` clause is set to a
 single post type, I don't think it's a problem for this ticket which
 should allow some variation of the simpler patch to be used.

 `update_post_caches()` is only called if `$this->posts` matches the
 unfiltered value. If the posts have been modified then
 `_prime_post_caches()` is used which allows for any post type to be
 primed.
