Currently we support an images disabled mode in MobileFrontend.
We want to test a hybrid mode which loads images as required via JavaScript.
With a flag enabled e.g query string parameter
AND the disableImages cookie / mobileoptions feature enabled any disabled images should be pulled in via JS (when scrolled to - see getBoundingClientRect / debouncing). Ideally it shouldn't need to do API requests.
You may need to update MobileFormatter to do this.
