Just the opposite. Marker is the only overlay that does not return
MouseEvent. According to documentation and in real life.
MouseEvent object is returned by mouse events of:
- Polyline
- Polygon
- Circle
- Rectangle
but not by Marker. Clicking the above listed overlays also causes a
Map 'click' which returns a full MouseObject with 'pixel' property as
well. Clicking on Marker prevents Map 'click' event.
