Thanks to someone for the request that I provide the offending source, but
I'm on another project right now.
I suspect the issue boils down to with my code the geometry math puts the
menu such that the mouse is over the first item when the tip appears. Then
mouse-up selects the item.
The fix is to get the geometry right, putting the menu a pixel southwest of
the mouse, and maybe to trigger the context menu on mouse-up instead of
mouse-down.
