Apply owner scale to attributes adds drag to particles.

I have just noticed this in a project we are doing.

If you create a default fountain particle effect and disable drag and gravity, then add apply owner scale attributes node. You will notice the particles suddenly to not travel as far. From what I can tell, the apply owner scale attributes node adds drag to particles. (Ticking drag and forces within the node does not fix it.)
The only way I can find to kinda fix it is to add a drag node, and set this to zero, and put the apply owner scale attributes node underneath the drag. Am I doing this wrong? Or is this a bug?

Thanks
