I have tried to debug it some more..

There seems to be two bugs:
- if you ctrl-click a row, the row is not marked as selected before the WhenSel callback is called.
- if you ctrl-click to deselect a row or to select a row when there is no previous selection, the WhenSel callback is not called at all.

I did find a workaround, which is to use WhenAction instead of WhenSel. WhenAction is called once when the cursor moves and then once again after the selection is updated. The only problem is that since it is called twice it does all the heavy lifting of updating my plot twice every time (it seems fine with my current dataset, but could potentially be problematic with a larger one).
