Issue: (in Area) images under "pages in X" and "Categories in X" never load on mobile

As I mentioned in a different report, changing the icons in the content list would actually require significant changes that could break things for a lot of users, so it will have to be done in a big release like 4.2.x.

Let's ignore the fact for now that these icons should not even be lazy if you actually have lazy-loading turned off.

I think the problem with the images not loading actually has nothing to do with the images themselves, but rather that there appears to be another Javascript that runs and breaks on narrow widths. Once one Javascript breaks, some browsers stop running all other Javascript too, which could explain the behavior you are seeing. The other Javascript is another VaultWiki component; I will update you once I figure out what's happening there.

Fixed an issue in the contentlist JS for the next release where it was possible for the last statistic in a row to be collapsed, with would throw an error on the next line. However, your icons are loading now without that fix, so it probably had to do with one of the other thumbnail issues you were having.
