first image is not lazy loading in image grid

Hi,

I use Lighthouse to check my website and it said some images are not lazy load, so I check the HTML source code and found that every first image of “SiteOrigin Image Grid” Widget does not use

loading="lazy"

I tried to fresh install new WP with SiteOrigin, the problem still there. Here is the testing page. You can see those 3 images are below the fold, so they should be lazy load. May I know if this is a bug of “SiteOrigin Image Grid”?

Below are the related codes
