Comment (by westonruter):

 @dennysdionigi yes, I'm well familiar, which is why I'm confused why I'm
 not seeing that loading the modules with low priority is not improving LCP
 on a page that has an image with `fetchpriority=high`. I'm sure I saw an
 improvement when I tested before. We need to put together a test page that
 shows consistent performance improvements.
