Comment:

 In [changeset:"50682" 50682]:
 {{{
 #!CommitTicketReference repository="" revision="50682"
 Media: Do not lazy load hidden images or embeds.

 Improve the check for sourceless or dimensionless media when determining
 if the lazy loading attribute should be added to iframes and images. Never
 include the lazy loading attribute on embeds of WordPress posts as the
 iframe is initially hidden.

 Including `loading="lazy"` on initially hidden iframes and images can
 prevent the media from loading in some browsers.

 Fixes #52768.
