If I have an infinite scoll list in an active tab that’s currently loading more elements, and I switch to another unrelated tab, the first infinite scroll will keep loading elements. It’s especially problematic since it always thinks the is on-screen, so it never stops.

Watch the console.log statements. If you stay on the initial tab, it stops loading more when it gets to the bottom. If you switch to the second tab after it loads a couple, it keeps loading (slightly bad) and doesn’t stop even when it’s beyond the bottom of the page (quite bad).
