Sunburst figures not aggregating custom_data for parents with >1 leaf

Consider the following Sunburst figure:

import pandas as pd
import plotly.express as px

data = [
    ["A", "1", 200.0, 20.0],
    ["A", "2", 100.0, 10.0],
    ["A", "3", 350.0, 35.0],
    ["B", "1", 500.0, 50.0],
    ["C", "1", 20.0, 2.0],
    ["C", "2", 50.0, 5.0],
]
columns = ["Category Group", "Category", "Value", "Additional Value"]
df = pd.DataFrame(data, columns=columns)

fig = px.sunburst(df, path=['Category Group', 'Category'], values='Value', custom_data=['Additional Value'])
fig.update_traces(textinfo="label+percent entry")
fig.update_traces(hovertemplate='<b>%{label}</b><br>Value: $%{value}<br>Additional Value: $%{customdata[0]}<br>')

Any parents with >1 leaf do not display the sum of their children for the custom_data field. This behavior is not in line with other fields such as value or color which correctly display the sum of their children

Riproduci il caso con il pandas DataFrame fornito e px.sunburst(..., custom_data=...). Traccia come vengono generati i valori parent per custom_data rispetto a value e color, partendo dal punto di ingresso px.sunburst e arrivando al trace della figura risultante. Il lavoro è completato quando parent customdata mostra la somma dei relativi valori foglia, inclusi i gruppi A e C, preservando il comportamento esistente.
