RadioBoxGroup Styling not working in FastTemplate

[MarcSkovMadsen]

I'm on Panel 1.0.4 and trying to help a user that wanted to migrate from Streamlit to Panel in https://discourse.holoviz.org/t/migrate-from-streamlit-to-panel/5463.

As you can see below the RadioBoxGroup is not usuable with the current styling. It used to work.

import time
import panel as pn

pn.extension(sizing_mode="stretch_width")


def calculation_a():
    time.sleep(1.5)


def calculation_b():
    time.sleep(1.5)


calculation = pn.widgets.RadioBoxGroup(
    name="Calculation",
    options=["Calc A", "Calc B"],
    button_type="primary",
    button_style="outline",
    inline=True,
)

component = pn.Column(calculation)

pn.template.FastListTemplate(title="Calculation Runner", main=[component]).servable()
