Parameters
- e

The event data.
Remarks
The Ribbon should not take keyboard focus from the application. This method overrides the default behavior and temporarily sets the Focusable property to false, which prevents the control from taking keyboard focus. It then calls the base method.
This implementation does not change the handled state (the Handled property) of the MouseLeftButtonDown event data.
