This is a pretty cheap way of fixing this bug by saying nsDocShell::loadURI calls done with a system principal will add user interaction to the current page. This takes advantage of the fact that all UI code for loading URIs goes through this code path. Note that during debugging I've found other cases where SH entries would be added with a system principal, most notably when navigating to URL hashes/fragments (example.com#hash). I'm not sure why this is happening but it doesn't go through nsDocShell::loadURI. Differential Revision: https://phabricator.services.mozilla.com/D127558
