reopen notebook ipywidget in jlab - Error creating widget: could not find model

See original GitHub issue

I am using:

JupyterLab v0.26.5
@jupyter-widgets/jupyterlab-manager @0.26.0
ipywidgets-7.0.0
widgetsnbextension-3.0.0

I created a notebook with Jupyterlab and some ipywidgets - Textbox and int slider. When I close the notebook and reopen the notebook, the kernel is still attached but the widget has disappeared and instead shows:

Error creating widget: could not find model

In the notebook, when I close the notebook and reopen it the values in the Textbox and slider are persistent and do not get deleted. Here, to even see the widget again I have to re-run the cell
