Changeset 55093 for trunk/tests/phpunit/tests/post/thumbnails.php

Message:

Media: Allow for customization of lazy-loading featured images.

When lazy-loading images was introduced, in [52065] the check for wp_lazy_loading_enabled() was omitted by accident in the logic to set the attribute with its default value on img tags from get_the_post_thumbnail(). Without this check, it is impossible for third-party developers to modify the behavior for featured images.

This changeset fixes the problem by introducing the check.

Props flixos90, joemcgill, mukesh27.
Fixes #57490.
