Comment (by joemcgill):

 In [changeset:"41732"]:
 {{{
 #!CommitTicketReference repository="" revision="41732"
 Customizer: Minimize duplicate header crops in the media library.

 This adds `Custom_Image_Header::get_previous_crop()`, which finds any
 previously cropped headers created from the same base image and replaces
 that attachment rather than creating a new attachment.

 After updating a crop, the replaced images is also removed from the list
 of previous header images in the Customizer.

 See #21819.
