Description of expected behavior and the observed behavior

The panel button.loading=True is not working as expected in deployed app. It works fine in a jupyter notebook though. Check the gif below:

      submit_button = pn.widgets.Button(name='Submit', width=100)

      def on_click(event):
          submit_button.loading = True
          hint_box.object = 'Loading'
          hint_box.alert_type = 'warning'

          time.sleep(5)

          submit_button.loading = False
          hint_box.object = f'Clicked {submit_button.clicks} times'
          hint_box.alert_type = 'primary'

      submit_button.on_click(on_click)
      return pn.Column(hint_box, submit_button)

Could you try again with 0.13.0a42? I think #3231 should have addressed this.
