Dragging one of the premade particle effects from "Qt Quick 3D Particle Effects" section in component library highlights particle emitters in navigator

Add a particle system with emitter to the scene and expand it in navigator. Then start dragging one of the premade particle effects from "Qt Quick 3D Particle Effects" section in component library. The particle emitter in navigator highlights as if it was a valid target for the drag, but there is no property in particle emitter that sensibly accepts the premade particle effect as a child item of the emitter.

The incorrect highlight is probably related to "system" property the emitter has.
