After enabling forward shading, having two planar reflections in the scene causes one instance to not render properly.
Tested in 4.22.3 (CL - 7053647), 4.23.1 (CL - 9631420), 4.24 (CL - 9828119), 4.25 (CL - 9828147)
Expected: Both Planar Reflection captures should be showing the mesh
Result: Only a single instance shows the reflection
