Multinode Picker 'Open' preview feature

[jap64]

I'm using the Nexu relation viewer on a document type and when I view on a node it works great, it shows me where the node is being used.

I also have the same node type used as the source of a multinode treepicker, the multinode treepicker has a handy 'Open' button which allows you to see the content of the picked node in a side view popup. The Nexu relation viewer is not being populated in the side view popup, from what I can see it make the 'GetIncomingLinks' call but uses the contentId of the parent node. Not sure if it can instead detect the fact that it's in a popup and use the relevant contentId?

Thanks
