Clustergrammer2 0.5.2 not working in Jupyter Lab (JLab)

[cornhundred]

Clustergrammer2 version 0.5.2 changed the package.json in the following manner:

"@jupyter-widgets/base": "^1.1.10 || ^2", see commit

This change was recommended here: jupyterlab/jupyterlab#7063 (comment)

This change was described in the widgets documentation here and quoted below:

Updates for Widget Maintainers
Custom widget maintainers will need to update their @jupyter-widgets/base dependency version to work in JupyterLab 1.0. For example, if you had a dependency on @jupyter-widgets/base version ^1.1, update to ^1.1 || ^2 for your widget to work in classic notebook, JupyterLab 0.35, and JupyterLab 1.0. See #2472 for background.

jupyter-widgets/ipywidgets#2472 can be found here.

In my testing on a local JLab 1.0 and MyBinder JLab 0.35.4. I'll summarize the experiments below:

Changing the version of jupyter-widgts/base to ^2 allows Clustergrammer2 to work in JLab >1.0 and Jupyter Notebook. However, Clustergrammer2 is no longer running in JLab < 1.0 - we would like to address this but are alright with requiring JLab > 1.0.
