offset not working towards the end of the page

[allonsacks]

If I change the offset like
offset: 800
I see in my networks tab the images loading 800 pixels before I reach them but any images towards the end of the page I am guessing less than 800 pixels before the end of the page only load just before I reach them. This is on scrolling. If I resize the window when I expect the image to have loaded it does actually load. Also on page load. So the issue is only when scrolling it ignores the offset.

I have the exact same issue as well.
