Cannot style map a hierarchical Tabulator

[CTPassion]

ALL software version info

panel 1.3.2 python 3.11.4

Description of expected behavior and the observed behavior

Expected: The style.map method applies in exactly the same way that it does to a tabulator when Hierarchical=False.

Observed: The map method does not style the table cells when Hierarchical=True.

Complete, minimal, self-contained example code that reproduces the issue

import bokeh
import panel as pn
import pandas as pd

bokeh.sampledata.download()

df = pd.read_csv("C:\\Users\\J01024\\.bokeh\\data\\routes.csv")

df = df.set_index(['Airline', 'Source'])

table = pn.widgets.Tabulator(value=df, hierarchical=True, height=200)

table.style.map(lambda x: "background-color: red;")

table.show()
