[Dragon] Hide toolbar on multiscreen setup
Review Request #127704 - Created April 21, 2016 and submitted
If cursor leaves screen after been on toolbar, it stays shown. We don't need to handle enter event cause mouse event makes that work.
Tested on my multiscreen setup.
1. Leave screen when cursor was out toolbar - works.
2. Leave screen when cursor was on toolbar - works.
3. On one screen - still works.
