Looks like a bug.  Should be MouseDown, Selection everywhere to be consistent 
with controls such as List.

To be exact, Selection should follow MouseDown for native controls.  It is 
unspecified whether Selection comes before MouseUp.

Fixed so that we now get MouseDown, Selection detail = 1, ... Selection detail 
= 1, Selection detail = 0, Mouse Up.

Needed to add the tracking code to Slider.  In addition to fixing the bug 
reported here, this fixed the fact that there was no mouse up.

Fixed for 3.1 in HEAD > Nov 24.
