Feature Description

The Auto Sizes plugin adds sizes=auto to all images with loading=lazy. This is all done server-side without knowledge of which images are actually in the initial viewport across breakpoints. This is knowledge that Optimization Detective has from user visits. In #1077 images which are not in any breakpoint group's initial viewport will be lazy-loaded. However, the addition of loading=lazy to these images should also include sizes=auto. This could be done in the same "Image Loading Optimization" (Image Prioritizer?) dependent plugin of Optimization Detective, or better it could be incorporated as part of the Auto Sizes plugin instead.
