Expect references to `__init__` method to show me references of constructor

• Go to https://sourcegraph.com/github.com/joxeankoret/maltindex@6bbbb67eaca104aea7782f2e9ba1a1479c316074/-/blob/diaphora_index_batch.py?q=CBatchRunner#L28:7-28:15
• Click "find references" on CBatchRunner's __init__ method. I'd expect the results to show me invocations of the constructor. Instead, I see no results.

Hmm, this seems to be another case that Jedi doesn't handle as expected, so we'll need to write some custom logic.
