When I'm on an unstable network connection and load a page with images hidden under expandable sections, e.g. https://en.m.wikipedia.org/wiki/Spherical_coordinate_system , Firefox loads the images which are immediately visible on the page. But after I expand one of the sections when the network connection is lost (this can be simulated by turning off Data Connection before expanding the section), the images are not loaded, which is somewhat expected. What is unexpected is that I couldn't find any way to force reload these failed images when network connection is restored (except by reloading the whole page, which will again take some time, after which network connection may be lost again). So, how can I reload these images without reloading the whole page?
