Button widget: format does not match spec

[thuydotm]

Looks like button style is always contained regardless what its value is. Button color (button_type) is correct though.

import panel as pn
from panel_material_ui import *

pn.extension(template='material', defer_load=True)

button_styles = ['contained', 'outlined', 'text']
button_types = ['primary', 'secondary', 'error', 'info', 'success', 'warning']

for s in button_styles:
    for t in button_types:
        button = Button(name=f"{s}-{t}", button_type=t, button_style = s)
        button.servable()
