Left side frozen columns data scrolls with unfrozen columns when scrolling goes beyond initial width of tabulator pane width.

Thanks for the great work continuously being done by developers and contributors of panel! I noticed one issue I wanted to make you aware of (though it is also mentioned in other issue, as pointed to below).

Software Version Info

Description of expected behavior and the observed behavior

Data in frozen columns are expected to stay frozen all the time when scrolling horizontally.

Currently the data in frozen columns to the left starts to slide with data in unfrozen columns when scrolling goes beyond initial pane width.

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

Store the below into file named frozen_column_data_issue.py
Run panel serve frozen_column_data_issue.py

import panel as pn
import pandas as pd
import random
pn.extension('tabulator')

data = {f'col_{chr(97 + k)}': [random.randint(0, 100) for _ in range(20)] for k in range(10)}
df = pd.DataFrame(data)

tab = pn.widgets.Tabulator(
    df,
    width=400,
    # sizing_mode='stretch_width',
    frozen_columns=list(df.columns[:2]),
    theme='fast')
tab.servable()

The issue is also mentioned in #7543

The fix by https://github.com/broccoliboy --> #7543 (comment)
works in my case too, but ideally it is not needed.
