Isn't this a situation where the runner getting obstructed as she is "just shy of 3B" as the OP states grounds for considering the OBS happening between third and home? After all, if she was trying to round third to go home, the OBS prevented that.

And if that was the case, she cannot be put out at home. She would be returned to third if she's tagged out at home by a good margin.
