Comment (by flixos90):

 In [changeset:"48272" 48272]:
 {{{
 #!CommitTicketReference repository="" revision="48272"
 Media: Improve support for opting out of lazy-loading for template images.

 With this changeset, in addition to the already present
 `wp_lazy_loading_enabled` filter, developers can now opt out of lazy-
 loading template images via `wp_get_attachment_image()` by passing a
 `loading` attribute with boolean value `false`. This can be used e.g. by
 theme developers on images which are very likely to be in the initial
 viewport.

 This changeset also improves related test coverage.
