Via #2831302: Hide Tab if view is empty → a feature was introduced to hide the tab if a view returns no results. However, this does not take into account the "no results behaviour" in views. For example, if I want to display some "no results text" when the view is empty, this does not work because Blocktabs simply hides the view and ignores the settings about what to do if the view has no results.
