PTAL.

Not sure what to do with this one. The code doesn't make sense if _Group isn't
used, but _Group, currently, isn't used.

Should we leave it and try to figure out how it gets set, or remove it and
patchup the calling code?

I'd leave it for the moment.  Lotta disruptions lately, might be good to see if
any other embedders hit issues after pulling head branch.
