Unfortunatly this is not the case. I've added a mouselistener that
prints to console, it's never called.
Please try to run the snippet below.
This can be reproduzed both on 3.3. and 3.4.
Or maybe I'm just missing something ?

It's not a MouseListener its a double-click listener on the Viewer.
Here's a corrected version giveing you the double clicked cell.
