How to fix a jumping Collapsing Toolbar?

Question

When I scroll a screen then Collapsing Toolbar start bounce.

My problem on video — video

When I pull the toolbar first, then the content, the toolbar starts to jump. If you just pull the content, everything works well. But the picture in toolbar is long, the user will often drag the image (toolbar). It would not be desirable, that user has jumped toolbar. Does anyone know what can be done with this?
