[Python] Spinner of Shiny Python does not show up for output_table

I’m trying to create a busy indicator while generating a table using ui.busy_indicators. However, the spinner does not appear when using ui.output_table. If I replace ui.output_table with ui.output_plot or ui.output_data_frame, the spinner works as expected. This makes me wonder if ui.busy_indicators is incompatible with ui.output_table.

import time
import numpy as np
import seaborn as sns
from shiny import App, render, ui
import pandas as pd

app_ui = ui.page_fluid(
ui.output_plot("plot"),
#ui.output_table("table"),
ui.busy_indicators.use(),
)

def server(input):

@render.plot
def plot():
time.sleep(3)
sns.lineplot(x=np.arange(100), y=np.random.randn(100))

@render.table
def table():
time.sleep(3)
df = pd.DataFrame(np.random.randn(10, 10), columns=[f'col_{i}' for i in range(10)])
return df

app = App(app_ui, server)
