composer overlay and google.iap.v3

I’m setting up the in-app purchases for my next app and wanted to use an overlay for the store screen.  The trouble is whenever a purchase is successful or cancelled the overlay scene is destroyed shortly after.  This is happening with composer and google.iap.v3 right now.  I haven’t tested on iOS yet so I don’t know if it has the same behavior there.  I’ve commented out all the composer.hideOverlay() commands in the scene so I don’t see how it could be a tap or touch event falling through.  

Has anyone else run into this kind of behavior?

Edit:  Just confirmed I get similar behavior on my iPhone 5.
