Trying to create a new Tab in the Tab Bar I am getting a message about not being able to split a Window:
What does Window mean in this message? I ask for a new Tab and not for splitting a Window.
The described behavior is the same no matter in which way creating a new Tab was requested. So both, clicking the rightmost + in the Tab-Bar and choosing 'New Tab' from File-Menu give the same outcome.
