It looks like when I run this against tp32 without
`MatchPredicateStrategy`, the `a` and `b` keys are missing from the results. I
think I figured out what the issue is. Without `MatchPredicateStrategy`, the
wheres are not integrated into the `MatchStep` so `PathRetractionStrategy` sees
that `a` and `b` are not referenced after the match so they are dropped. I'll
make an update so that if this pattern is seen, the match start and end labels
will be preserved in the same manner as they would be with a traversal where
the `MatchStep` was the terminating step.
