Activating light gizmo causes light to move

[Drigax]

Bug repro: https://www.babylonjs-playground.com/#9DXCHP
Expected result: The light gizmo should have no effect on the light direction.
Current result: When scene is returned immediately (no export at all), the light gizmo toggle reverses the light direction (direction = -1 * direction).
Comments:
This bug does not occur in playground #KX53VK#27 (left handed).
This bug does not occur in the sandbox (playground #9DXCHP exported using Inspector tool).
The light is initially oriented front to back (0,0,1).

as a note, this bug is not related to handedness. this can be reproduced in a left handed coordinate system as well, since the default gizmo is aligned with the world origin. Any transformed light will be reset to point to local origin once activated.
