Possibly a collision detection bug (BabylonJS built-in collisions)

Hi there

I got the following problem:

in short: My meshes are colliding on boundingBoxes (using mesh.intersectsMesh(otherMesh) rather than the actual meshes.
I saw that in @jsdream 's example the collision doesn’t depend on the boundingBox,( but rather on the edges?), but I can’t figure out why exactly? Does this only work with moveWithCollisions()?
