I've looked at this some more.  In feta-noteheads.mf, line 39, we do

save black_notehead_width

which establishes black_notehead_width as a local variable to the group.

It may be as simple as eliminating the save statement for
black_notehead_width.

Alternatively, it may involve expanding the group, instead.  But I haven't
worked that out yet.

HTH,
