Group movement distorts with scenes of different scale in actor blueprint

There is an issue with selecting multiple meshes that are children of different scenes when the scale is different than the default. moving the static meshes together causes them to move at different rates. This issue does not appear to be a regression.

Versions Tested: Issue occurs in all versions tested
4.17.2 - CL: 3658906
4.18.1 - CL: 3754814
4.19.0 - CL: 3776583

1. Create a new project (no template or starter content needed )
2. Import the static mesh file provided
3. Create a new Actor class blueprint > name it "TestBP" > Open TestBP
4. Add two Scene components as children of the default root and set the scale of each to 2 for all axis
5. Add a static mesh child to each scene and align them so they are parallel
6. Select all static meshes and move them on the z axis (up and down)
   Result: The meshes do not move at the same rate despite being the same size
   Expected Result: The meshes move at the same rate
