some floating point inaccuracy appear to influence actor positions when moving actors back and forth in only one axis in the level viewport. It is especially noticeable when the actors are far from the origin.

Steps to Reproduce
  1. Open Editor
  2. Place two static mesh actors around 100000, -240000, -6000
  3. Change their Z rotation to 45
  4. Attach one to another
  5. Change the rotation mode to Actor Space
  6. Uncheck grid snapping
  7. Grab the child actor's X move axis and move it back forth repeatedly
    (Seemingly dependent on camera angle) the actor will move in a different axis over time

Expected: The static mesh would only move along one axis
Result: The Static mesh seems to move on two axis (depending on camera angle seemingly)
