Does not work with ipywidgets 7.8.0

[mofojed]

I would like to be able to use deephaven-ipywidgets with 7.8.0

[mofojed]

Tried it out, the error I'm getting:

272.2c7a2a1ef6d577414e03.js:1 Failed to fetch ipywidgets through the "jupyter.widget.control" comm channel, fallback to fetching individual model state. Reason: Control comm was closed too early
