Does not go to def, even with modifier key change

[JulianSMoore]

MWE: new notebook

Cell1: def HiW():
print('Hello World!')

Cell 2: HiW()

With default modifier (Alt) the jupyterlab selection cross appears and click does not go to the definition of HiW() (after cell 2 has been run). Same if modifier is changed to Ctrl, or Shift, or Meta...

Ctrl +Alt + B also does not do anything.

Extension was added using the built-in extension manager and is shown as installed; note that there was no "rebuild" on the last occasion it was installed... I do believe there was a "rebuild" the 1st time it was installed but since it didn't work then I uninstalled it. I repeated the installation after updating to JupyterLab 3.1

Installation Details:

Note that the Chrome browser in use has NoScript, ABP, Ghostery and UBlock origin plugins, however: ublock origin is disabled for localhost, localhost is trusted by Ghostery, ABP is disabled for localhost, and NoScript is set to trust localhost and npmjs.org .

I am not updating this extension any longer it won't work with current JupyterLab - please use https://github.com/krassowski/jupyterlab-lsp instead
