tdf#127552 Make toolbox highlighting behave as intended
This patch provides intended highlight behavior to my understanding of
comments found in the toolbox source code.
*only highlight when the focus is not inside a child window of a
toolbox eg, in an edit control
*do not highlight when focus is in a different toolbox
*only clear highlight when focus is not in toolbar
