Babylon.js 7 (scene.useRightHandedSystem = true) - corrupts the camera state.

[julapy]

In Babylon.js 7 scene.useRightHandedSystem = true - does not work.
inspecting the camera.rotationQuaternion reveals NaN values.
works fine if useRightHandedSystem is false.

to replicate we have been using the github sample:
https://github.com/8thwall/web/blob/master/examples/babylonjs/placeground/index.js

• index.html - update babylon version to 7+ (ie, we're using 7.45.0)
• index.js - update BABYLON.SceneLoader.ImportMesh to BABYLON.SceneLoader.ImportMeshAsync (so it works in babylon.js 7)
• run with useRightHandedSystem = false - works.
• run with useRightHandedSystem = true - fails
• inspect the camera rotationQuaternion when using right handed system
