Description of expected behavior and the observed behavior

No matter how I set justify, column labels do not change. This is happening in boh notebooks and navigators.

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

import pandas as pd
import panel as pn

df = pd.DataFrame({"A": [100000000000000000,2,3], "B": [2,3,4]})
pn.pane.DataFrame(df, justify="left")  # Here I would expect "A" and "B" appear at the left margin within its column space
