Wondering why Lighthouse is recommending you to fix this, although you don't see any layout shifts yourself, and why is it warning you only now and not before?
To lazyload or not to lazyload images? From a user and performance perspective, you should lazyload images, but should you use a JS library?
Browsers are always trying to optimize as well. Some browsers already support lazyloading of images and iframes, using the loading attribute.
