When you open a diagram, it will create a new tab, even if it is already open. Thus, multiple tabs may show the same diagram

Which "open" are you speaking about ?
There is several ways to open a diagram, from several places.

In  general this is not a bug, this is a required behavior. Once can require having a diagram open several times, for example to be able to watch in one glance two different areas of the same diagram.

From the sashwindows system point of view, the open() method is designed to open a diagram tab. It doesn't check if the diagram is already open in another tab. It is your responsability to check if the diagram is opened before calling the method open(). The IPageMngr provide an isOpen() method for this purpose.
From a command point of view, you can do what you want: check if a diagram is already open or re-open it anyway.
In the ModelExplorer, the open command title change according to the fact that the diagram is opened or not. The title is:
-  "open" if the diagram is not open
 -  "open in new tab" if the diagram is already open

Precision: I talk about the opening of a diagram from the model explorer. The default behavior of a double click on the diagram should be to open it or activate if not already open. Whereas it is sometimes useful to open multiple views of the same diagram, the default behavior (i.e. the behavior associated with a double click) should be to activate an already opened diagram.

I'm currently working the model explorer view. This bug will be corrected with the following enhancement see:
