Speeding up lazy load effect with anchors

I like the lazy load effect and used it for many elements of our homepage. Most pages have sub-menus to navigate on site via anchors.

When the visitor scrolls down the page the first time, he/she sees the desired lazy loading effect.

When the visitor loads the page and uses the sub-menue to navigate to content at the bottom of the page, it takes quite a while until the elements appear. Reason seems to be that all the lazy elements are loaded top to bottom in sequential order and if the page is long it takes a while until all (actually not visible) elements above the desired content are loaded.

There’s also a further lazy load issue when combining anchors and masonry galleries. As the galleries expend with loading its content/pictures, quite often the anchor content moves out of focus. Only when all the content has been loaded the anchor works correctly.

What I was wondering is whether there’s a way to speed up the loading of these hidden elements? So that there’s just the regular wait for the elements of the anchored bottom elements.
