GetHolesLODInfo doesn't match the content of the HeightmapSubRegion holes array

Terrain

-

Heightmap::GetHolesLODInfo returns kPatchHasSurfaceOnly for the patch I am interested in, but after extracting the HeightmapSubRegion the m_RawHoles are all 0 which means hole.

1. Download and extract this repro project: https://drive.google.com/file/d/1o5pdHh4roLg3tmj_1aJ0z4bMDo1kOIFa/view?usp=sharing
2. Compile an editor from https://ono.unity3d.com/unity/draft/changeset/f38b769664a471f66a9aeea3ca6cf6885c4ecb06
3. Open t1 scene;

Expected result:
One of the LOD related asserts should fire if the patch is fully covered by holes, but the returned holeInfo is kPatchHasSurfaceOnly:
Assert(holeInfo != Heightmap::kPatchHasNoSurface);
Assert(holeInfo != Heightmap::kPatchHasDirtyHoles);

Actual result:
Assert(holeCount != m_HeightmapSubRegion.m_RawHoles.size()); fires (entire patch is covered by holes).

The patch in question is (0,1) which corresponds to UV bounds 0.0, 0.25, 0.25, 0.25.

Notes:
This issue is preventing GI baking from working.
