Comment:

 In [changeset:"56143" 56143]:
 {{{
 #!CommitTicketReference repository="" revision="56143"
 Media: Ensure that large images before the main query loop are counted
 towards lazy-loading threshold.

 Following [55318], [55847], and [56142], certain images in the header of
 the page have received support for potentially receiving
 `fetchpriority="high"` and having the `loading="lazy"` attribute omitted.
 However, these images being present did not affect the "content media
 count" which counts the images towards a certain threshold so that the
 first ones are not lazy-loaded.

 This changeset also increases that count for such header images if they
 are larger than a certain threshold. The threshold is used to avoid e.g. a
 header with lots of small images such as icon graphics to skew the lazy-
 loading behavior.

 Props thekt12, spacedmonkey, flixos90.
 Fixes #58635.
