Scaling issue, causing small gaps in between scaled meshes.

I was attempting to make a level out of the cubes (on grid) but, I found weird gaps in between areas, and it was really bugging me.

I found after much testing that if a mesh is scaled negatively on one axis, and positively on the other, you start getting very subtle weird scaling issues in the negatively scaled axis. This is really annoying. (I tested it with a default UE5 cube, and also with a cube from blender)
