It should use the closest dispatch as you describe.

The Dispatcher1D code is not very well tested and is possibly broken
(sorry, Janek). I will have a look tonight and fix it.

In Dispatcher2D, on the other hand, the logic was rewritten by me and is
tested to handle all such cases correctly -- see e.g.
scripts/test/dispatch-torture.py (I just fixed it in the last commit) --
