One needs to scroll a specific distance past an element for it to animate ("fade-in" for example). If one uses Elementor to create a template used in a theme's footer widget space for example, the animation may never fire.

This had me stumped and had me thinking the code wasn't executing and then I realized the html/css is all there, just not the trigger event to actually see it. I don't have any suggestions on what to do here but have since gone around the problem by removing the animations from the elements until there is a better approach.
