Comment (by whyisjake):

 In [changeset:"50040" 50040]:
 {{{
 #!CommitTicketReference repository="" revision="50040"
 Media: Ensure that wp_get_attachment_metadata can return values from the
 global $post, if avaiable.

 In [49084] (for #50679), wp_get_attachment_metadata() was changed to
 improve performance, but it had the side effect of eliminating the ability
 to call it with no arguments and have it default to using the global
 $post.

 This change restores that ability, while keeping the performance
 improvements from the original change.

 This changeset brings [50039] to the 5.6 branch.

 Fixes #52196.
