map_values does not work?

pyjq==2.4.0
jq version: 1.6

I wanna filter some certain objects with jq. Seems there's a bug with map_values function.

With jq, it works fine:

echo '{"a": {"status": 1, "elapsed": 12}, "b": {"status": 0, "elapsed": 11}}' | jq 'map_values(select(.status==1))'

returns:
{
  "a": {
    "status": 1,
    "elapsed": 12
  }
}

But with pyjq:

data={"a": {"status": 1, "elapsed": 12}, "b": {"status": 0, "elapsed": 11}}
pyjq.first('map_values(select(.status==1))', data)

returns
None

Try
pyjq.first('map_values(select(.status<1))', data)

returns
{'b': None}

pyjq.first('to_entries| map(select(.value.status==1))', data) will work
