Maya skeletal animation export breaks when model is posed.

When exporting a scene that includes a skeletally animated model, if the scene is exported with the playhead set to a frame where the model is deformed, the exported model appears skinned using the rest pose skeleton rigged to the deformed mesh, or the deformed skeleton rigged to the rest pose mesh:

Exported from Bind pose frame (Frame -10):


Exported from Frame 80:

Download the linked Exporters_737.zip testing scene and reproduce the export with the playhead at the bind pose frame (-10) and frame 80. Compare the exported skeleton and mesh in both cases; done means the exported model keeps the skeleton and mesh deformation in sync when exporting from a posed frame.
