PowerPoint writes autoRev on p:cBhvr/p:cTn, not the effect node, so Grow/Shrink with auto-reverse grew and held. Color Pulse writes it there as part of the effect and is left out. Tests patch autoRev onto the behaviour node of a saved deck and read it back. Not checked against real PowerPoint: no PowerPoint COM here.

//! "Auto-reverse" is written by PowerPoint on the behaviour time nodes, not on the effect node.
