Regression checked in //UE4/Release-4.26.2 CL15973114 and the issue does not reproduce there

• Create a New empty raster project
  • If starter content is not present, add some simple shapes such as large cones or cylinders
• Add reflection plane
• Move RP above objects
• Notice the reflected chairs and floor, despite the objects appearing beneath the planar surface
