Broken filled area plot after interaction

This code gives us a beautiful plot:

import plotly.graph_objects as go

trace0 = dict(
    x=list(range(24)),
    y=[163, 154, 114, 61, 32, 19, 20, 20, 26, 38, 67, 102, 132, 159],
    name="Two",
    fill='tozeroy',
    stackgroup="one",
)
trace1 = dict(
    x=list(range(24)),
    y=[0, 8, 51, 108, 143, 164, 166, 168, 165, 152, 126, 80, 40, 11],
    name="Three",
    fill='tonexty',
    stackgroup="one",
)
trace2 = dict(
    x=list(range(24)),
    y=[0, 0, 0, 4, 19, 37, 49, 49, 39, 25, 7, 1, 0, 0],
    name="One",
    fill='tonexty',
    stackgroup="one",
)
data = [trace0, trace1, trace2]
go.Figure(data=data)

However, if we click on the legend in the following exact order [One, Two, Three, One, Two, Three], it breaks:

Same problem. After switching all traces off and on again the area plot looks like this:

The order of switching on and off matters.

Using plotly 5.6.0

I believe this bug was fixed by plotly/plotly.js#7668 and first released in plotly.py v6.6.0. Let us know if you still see this issue in the latest plotly versions.
