CallbackProperty callback not firing on clamped polylines using ColorMaterialProperty

[impactblue573]

Clamped to ground Polylines which use a ColorMaterialProperty based material do not update each frame.

Sandcastle Example

The issue seems to be caused by StaticGroundPolylinePerMaterialBatch.js not updating the material property when using ColorMaterialProperty.js.

Using a different material property such as PolylineOutlineMaterialProperty.js works fine.
