Morph Animations and glTF

Are morph animations available through Cheetah glTF export? The glTF specification does support these, and shape key animations from Blender work fine. But any animations in Cheetah made with the morph tag and exported to glTF do not appear to be working.
Cheetah3D pretty much supports the full glTF spec with one exception and that are morph targets. I want to add them in a later update.
