Comment (by flixos90):

 Lazy-loading an image in the initial viewport can have a negative impact
 on the Largest Contentful Paint Metric (also see https://web.dev/browser-
 level-lazy-loading-for-cmss/#avoid-lazy-loading-above-the-fold-elements).

 The change made in this ticket doesn't affect that though: The image not
 being lazy-loaded is maintained, it's only about the implementation, where
 passing `loading="eager"` is discouraged for the reason outlined in the
 description.
