      Description

      Obscure problem noticed when testing JAL-2374 patch.

      1. Load the example alignment (feredoxin.fa)
      2. create a group on the alignment (columns 21-50)
      3. Click drag to mark columns 10-19
      4. Right click an unselected and ungrouped region (say second row, column 5)

      Nothing happens - the popup menu is not shown because there is no selection under the mouse. (this is correct)

      5. now adjust the horizontal scroll bar to move the rubber-banded region off screen and then back on. Notice the rubber-banded region disappears, but the column markers stay. The sequence ID panel may also refresh to show that now there are no sequences selected.

      Two implications of this behaviour:
      * trashing the selection appears to be a bug, since the viewport doesn't update.
      * its probably not desirable to trash the users current selection because they right-clicked somewhere else. For a large alignment with thousands of groups this can also result in a slowdown because Jalview has to search all the groups to see if they intersect the region that was clicked.
