Comment (by westonruter):

 In [changeset:"61576" 61576]:
 {{{
 #!CommitTicketReference repository="" revision="61576"
 Customize: Use `wp_check_filetype()` instead of `substr()` to extract file
 extension.

 This fixes compatibility with image files that have 4-character
 extensions, such as `.webp` and `.avif`.

 Follow-up to [57524], [50810], [30309].

 Props buutqn, westonruter.
 See #51228, #35725, #21483.
 Fixes #64557.
