ipywidgets=8.0.5 breaks FigureWidget

[hmgaudecker]

The creation of FigureWidget below works fine with ipywidgets=8.0.4, but breaks in 8.0.5 with the error shown below.

import pandas as pd
import plotly.graph_objects as go

df = pd.DataFrame.from_dict(
    {
        "x0": {"0": -1.0, "1": -0.5},
        "y0": {"0": 0.5, "1": -0.5},
        "x1": {"0": -0.5, "1": 0.0},
        "y1": {"0": -0.5, "1": -1.0},
    }
)

arrows = [
    go.layout.Annotation(
        x=df["x1"][i],
        y=df["y1"][i],
        ax=df["x0"][i],
        ay=df["y0"][i],
    )
    for i in range(len(df))
]

fig = go.FigureWidget(layout=go.Layout(annotations=arrows))

Looks like ipykernel.comm.Comm was deprecated and ipywidgets updated it. See jupyter-widgets/ipywidgets#3533 and specifically this comment: jupyter-widgets/ipywidgets#3533 (comment)

No errors anymore with ipywidgets 8.0.6 and plotly 5.14.1, so closing this.
