7.1 background image lazy loading - how to stop it

Hi folks, in Squarespace 7.1 they've added a feature which loads the background image of a section only once you've scrolled to it. Generally, I really praise this move from Squarespace in order to make sites faster, but it is annoying when you reload a page you've already scrolled half-way down, and when you scroll up the images don't appear until the top of the screen is about 20% from the top of the image, so you're left with a blank area for the majority of the time scrolling through that section.

I used to be able to manipulate the imagesLoaded function in 7.0, but I don't know how to trigger Squarespace getting the image src in 7.1. 

Anyone know how to do this?

Thanks,

Andrew
