Cascade drag and drop and scaling changes based on docked location with high DPI

Scaling for Cascade changes when different particle effects become docked or un-docked to different windows. Drag and drop functionality is also skewed, as the module moves further than your mouse does.

Video example: [Link Removed]

In order to reproduce a high resolution display is needed. 3840x2160 was used in this issue.

1. Open up a project that has some particle effects
2. Open two separate particle effects and dock them all together
3. Un-dock one of the particles and move it to a separate monitor

Result: The scaling for the emitters changes and becomes very small

Expected: Scaling stays the same
