In the commit message, could you explain a little more about what the
bug was an how this is resolving it?

This is a bit of a nit, but but do we care if there is a lbinding for
this case? They seem to be orthogonal. Maybe it could be moved to the

Why is this change needed? It should work without this change?

I did some tests and it seemed to work as expected. Thanks Lorenzo.
