Pick up images loaded asynchronously

[rayrutjes]

Is there a way to access the JS lazy loader in order to manually trigger the loading of images that were fetched asynchronously?

This seems necessary when lazy loading posts on a page for example.

From documentation it seems it should be picked up automagically, however open tickets on forum seem to experience the same problem: https://wordpress.org/support/topic/lazy-loading-on-dynamically-added-content/
