[bug] Crash when try get relative pose in XRInputController between grip and ray #287

Open eXponenta opened 2 years ago

Emulator down with:

VM13:1284 TypeError: coordinateSystem._transformBasePoseMatrix is not a function

When i try read relative position between gripSpace and targetRaySpace. On real devices all ok and positions computed as should be.

Can be suppressed by try {} block in user code, but looks unstable.
