Subflow packaging as a module appears to be broken if the subflow includes a D2 ui-group config node as a subflow property.
Having packaged it up and installed it, on placing it on the flow, Deploying, and opening up the node to set the config all is well, but if I then select a ui-group node, deploy, and then re-open the node I see

The node does appear to correctly picking up the group, but it is not possible to get in to edit it any more.
I can put an example up on github for testing if it is not obvious what the problem is.
