Short description of error
When a node is linking update method of its tree is calling. In this method sockets which was connected has status 'is_linked' as True except group outputs nodes. I would expect that sockets of those nodes also would have True in is_linked attribute.
Exact steps for others to reproduce the error
- Open the file
- run the script
- after having made the links, the update callback will report 'is_linked' as False for the Group output node
