From TvW.

Reproduction:

• Open Preview Experimental Data workflow
• Open model
• Open trajectory/state for the model
• Scrub the model to some time (or not)
• Edit the model

Expected: the model is edited and remains in the current pose Actual: the model is edited, but returns to a default pose. The user must manually re-scrub to re-pose the model via the associated trajectory.
