Open 2 docs side by side.
In the left, run document-tab-list-buffers.
Press <Tab> (or single-click in the buffers list).
Click on the 2nd buffer window (where the buffers list is not open).
Bug1 : The list-buffers drop down window does not close.
Double click on any of the buffers in the list and the buffer in the other window changes.
Bug2: If the buffer list is open in Window1, then it should only change the buffer in Window1, not in other windows.
Bug3 (or feature?): Double click any of the buffers in the list. The list stays open. If instead you select a buffer in the list and press <Enter>, then the list closes.
