Comment (by mdgl):

 Note that the chosen solution here using `sanitize_mime_type()` breaks
 when presented with a comma-separated list of MIME types which is a valid
 return from `get_post_mime_types()`. The originally suggested fix of using
 `esc_attr()` works properly and seems more correct to me. See #30788.
