Mouse movements during Simulate will slightly move Skeletal Mesh actors that are simulating physics

Mouse movements during Simulate will slightly move Skeletal Mesh actors that are simulating physics. This also effects physics assets in the PhAT editor during simulate. The effect is small but I was able to reproduce it in 4.17 using the Third Person Character asset as well.

1. Open the attached test project
2. Simulate
3. Navigate the camera closer to the simulated assets
4. When the assets come to rest, move the mouse around the viewport

Results: The simulated assets will slightly move/jiggle when the mouse is moved around the viewport

Expected: For the mouse moving around the viewport to not effect the simulated asset in any way

Moving Mouse in Phat Editor while simulating causes unintended reaction
