Left nest with limit not showing limit in plan

In this test we check that the explain plan has limit = 10 in a certain location in the explain plan:

self.assertTrue(plan3["~children"][0]["~children"][0]["limit"] == "10")

index is: 

CREATE INDEX idx2 ON default ( _id  ) USING GSI

the query is:

select * from default b1 left nest default b2 on keys b1._id where b1._id like 'query-testemployee%' limit 10

the plan is:

{u'#operator': u'Sequence', u'~children': [{u'#operator': u'Sequence', u'~children': [{u'index': u'idx2', u'namespace': u'default', u'as': u'b1', u'keyspace': u'default', u'#operator': u'IndexScan3', u'index_projection': {u'primary_key': True}, u'spans': [{u'range': [\{u'high': u'"query-testemployef"', u'low': u'"query-testemployee"', u'inclusion': 1}], u'exact': True}], u'using': u'gsi', u'index_id': u'f6644ea3c276c9b4'}, {u'keyspace': u'default', u'#operator': u'Fetch', u'namespace': u'default', u'as': u'b1'}, {u'outer': True, u'namespace': u'default', u'as': u'b2', u'keyspace': u'default', u'#operator': u'Nest', u'on_keys': u'(`b1`.`_id`)'}, {u'#operator': u'Parallel', u'~child': {u'#operator': u'Sequence', u'~children': {u'#operator': u'Filter', u'condition': u'((`b1`.`_id`) like "query-testemployee%")'}, {u'#operator': u'InitialProject', u'result_terms': [{u'expr': u'self', u'star': True}]}, {u'#operator': u'FinalProject'}}}]}, {u'expr': u'10', u'#operator': u'Limit'}]}

relevant part of the plan is:

{u'index': u'idx2', u'namespace': u'default', u'as': u'b1', u'keyspace': u'default', u'#operator': u'IndexScan3', u'index_projection': {u'primary_key': True}, u'spans': [{u'range': [\{u'high': u'"query-testemployef"', u'low': u'"query-testemployee"', u'inclusion': 1}], u'exact': True}], u'using': u'gsi', u'index_id': u'f6644ea3c276c9b4'}

Maybe this is part of the index3 api changes?
