If you open context drawer like in example "about" it makes all other buttons unresponsive. So e.g. in cosmic-store you can change pages from Updates where you open context drawer, but then you can pick anything from other pages like applets, because buttons outside of context drawer don't work as long as the context drawer is open. It's extremely annoying. It think it shouldn't be default behavior. Either buttons outside of context drawer should work or clicking outside of it should close it.
