If I’m on a feed, say All, then I accidentally open the communities side bar, I cannot for the life of me work out how to close it without having to choose a feed or community, triggering a refresh.

This is worse when I’m on a post. I am here reading the comments in a post and accidentally open the communities side menu, how do I close it and stay on the post? I have almost no chance of finding that same post again 🙁
