Since we are doing bug reports here: images unexpand when I vote on posts
I don't know the right place to post bugs related to the nsfwpatch, but a new one here in 0.18 is that in any view, when I vote on a post, if there are expanded images on that post and any nearby, they collapse and the page scroll location gets messed up. It's super annoying.
The whole feature of auto expanding images is specific to this instance (it's a patch the admins added) so it doesn't apply to the main Lemmy repository.
