views blocks that were set to hide via "Hide block if the view output is empty: Yes" still renders the general structure of the view output. The view in question has a contextual filter "content: id" that is set to "Provide default value" -> content id from url. Fields are set to be hidden if empty. The rendered block doesn't show any output but creates the structure down to the views-row class.
How can blocks be completely hidden if there is no output? Seems like the "Hide block if the view output is empty: Yes" is without function at the moment, or?
