can not use stretch sizing modes within a modal

[wara6]

I thought it was resolved in this issue but I'm still seeing this problem.
I used various widgets inside modals and I saw there was generally a display problem when using stretch sizing modes (sizing_mode="stretch_height" or width or both). Here's an example with Tabulator widget but you can easely reproduce this with other widgets.

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

data = {
    'A': [10, 20, 30, 40],
    'B': [5.5, 6.6, 7.7, 8.8],
    'C': ['apple', 'banana', 'cherry', 'date'],
    'D': [True, False, True, False]
}

df = pd.DataFrame(data)

button = pn.widgets.Button(name='click me')
str_pane = pn.pane.Str("tabulator modal")
tab = pn.widgets.Tabulator(df, sizing_mode='stretch_height')
ui = pn.template.VanillaTemplate()
ui.modal.append(pn.Column(str_pane, tab))
ui.main.append(button)
button.on_click(lambda x: ui.open_modal())

ui.servable()

In this example, when sizing_mode='stretch_height' is used upon the tabulator, tha tabulator is disapearing from the display.

Reproduced with panel 1.4.0b3
