Thanks for the clarification, and that makes sense as a design, but
the bug is that this is not the observed behavior.  The calltip is
incorrectly dismissing itself when the cursor is within the tooltip
frame at the time of pop-up.

Based on a cursory insertion of 'print' statements, there is a surplus
of 'Leave' events triggered, which results in the calltip being
inappropriately dismissed while the cursor is over it.
