Free transform behaves different for vector smart objects - WHYYY???

[mschreiber1983]

I'm trying to perspective transform a vector smart object in PS CC 2015. SHIFT+OPTION+COMMAND+Corner Pull. Every other object pulls adjacent corners except for VSO's. Can someone please explain this to me? Is it not possible? Is it a bug? Is there some sort of logic behind this?

I'm not seeing this with PS 2017 and Win 10. ctrl-alt-shift does what you say.
