Fix stating point for drawing inline settings animation.

When a gear icon for the inline settings is clicked, the animation
should be drwan from the point where the mouse is cliked. However, if
notifications are shown on MessageCenterView, the animation is not
drawn from the correct point. This CL Fixes the stating point for
drawing animation.
