Dragging a component from Components view to 3D view doesn't clear highlights in navigator

For example, add a 3D particle system to the scene and expand it in navigator. Then drag a sprite particle from component library to 3D edit view. While dragging, the particle emitter highlights in navigator as a valid target for sprite particle item. However, when you drop the sprite particle into 3D view, the highlight stays on in the navigator. If you drop it to navigator or cancel the drag, highlight is correctly removed.
