Passwordstate Password Integration

I was bitten by the [unknown credential] issue using the 1Password rdf integration. Either missued it in the docs, or was not aware that specifiying a credential would lose me all those credentials after making the connection to 1Password (though in all fairness to me, the product does list it correctly when selecting it… e.g.

/rootdocument/1Password (Python)/credential_name

Is this still a bug, or are we supposed to use specify credential name? (which, btw, does not list the full path in case of name collisions)
