Gaussian splat problem with Right Handed System since 9.13.0

Hi,

When using scene.useRightHandedSystem the Gaussian splat meshes seems to have it’s depth (or alpha) sorting wrong.

PG right handed (wrong display): https://playground.babylonjs.com/#45KYTJ#144

PG without right handed (display ok): https://playground.babylonjs.com/#45KYTJ#145

9.13.0 with scene.useRightHandedSystem=true

9.13.0 with scene.useRightHandedSystem=false

8.56.0 with scene.useRightHandedSystem=true (same PG as before):
