ipywidgets not working in dev mode

See original GitHub issue

Hi,

I am getting this error on console when I run JLab in dev mode, while using ipywidgets:

import ipywidgets as ipyw
ipyw.Text("hello")

Uncaught (in promise) Error: Object 'jupyter.widget' not found in registry
    at default.js:1469
    at Promise (<anonymous>)
    at Object.loadObject (default.js:1448)
    at DefaultKernel._handleCommOpen (default.js:897)
    at DefaultKernel._onWSMessage (default.js:729)
    at WebSocket._ws.onmessage (default.js:653)

However it works perfectly fine when I start jlab normally. Any help with this?

Running JupyterLab in --dev-mode does not use any of the extensions.
