Description of the problem

This is a new behavior. S keyboard shortcut to save images that are being previewed has stopped working on old.reddit.com. I checked it on new reddit and it sort of works there. I checked on some other sites and it works fine there. I noticed that Reddit Enhancement Suite was using S for saving reddit threads, I changed that keyboard shortcut but that does not fix this issue.
