I made a 1x1 quad with a surface appearance on it with just some normals.
When I scale this quad, the lighting completely flips randomly.
I’ve included a test place.

Expected behavior
The quad should look the same no matter what the scale is.
Note: This is not the new edit mesh stuff, this is just a regular ol’ quad meshpart.
