> The decorrelator has a helper class called CorrelateProjectExtractor which
> moves projections from the right side of a Correlate to the left side.
> However, the helper ignores nested field accesses, assuming incorrectly that
> any field access is an input field access. Such expressions should also be
> moved to the left side.
