CheckLightMapUVs is not registering overlapping Lightmap UVs when it is called.

User Quote: "I have been working on an editor tool to diagnose some general asset problems and I noticed that in UStaticMesh there is a function to detect out of bounds / overlapping lightmap uv's but no matter what I do, I cannot get any errors for overlapping UV's, only out of bounds."

Steps to Reproduce
  1. Open the attached project
  2. PIE

Result: Only UVSuccessMessages is logged.

Expected: Based on the setup, it would be expected that MissingUVErrors and BadUVErrors would be populated, as the mesh in question has overlapping UVs.
