Python function "go to definition" and "peek definition" do not work

[eirik_morken]

When using notebooks with python in Databricks I would really like to easily see the defintion of the functions I am using within the editor. 
Which the "Go to definition (F12)" and "Peek definition" options when right clicking on the functions will help with.

However they do not seem to work for anyone on our tenant. 
It only displays "No definition found for 'test_function'" 
What could be the cause of this?

As per documentation this features only work when the notebook is attached to the cluster:

Make sure to attach to cluster:

And you can use the functionality:

If the notebook is not attached to the cluster, one gets the ""No definition found" message:
