`FigureWidget` fails with `anywidget` in colab

Problem:
Since v6.0.0 FigureWidget uses anywidget. However, it fails with a java script error.

import plotly.graph_objs as go
fig = go.FigureWidget()
fig.add_scatter(y=[2, 1, 4, 3])
fig

Either, no output (no figure) is shown or this is shown:

Workaround:
Downgrading to plotly-5.24 solves the problem

Maybe somewhat related to https://github.com/plotly/plotly.py/issues/4996

Reproduce the issue with Plotly 6.0.0 and anywidget 0.9.13 using the provided FigureWidget snippet, then compare it with plotly-5.24. Start by tracing the FigureWidget and anywidget integration; done means the figure renders without the reported JavaScript error in the affected notebook environment.
