Description of expected behavior and the observed behavior

Expected behaviour
Setting the disabled attribute of a widget to False should result in the widget being editable.

Observed behaviour
When the disabled attribute of widgets is set to True and then set to False, the attribute can be updated one more time and then fails to update further.

In the reproduction code below, clicking the Button named "toggle" once will see no change in disabled state. Clicking the "toggle" Button twice will see the state of the dummy widgets permanently set to disabled.

This behaviour occurs when the switching of states is done quickly (i.e. in a single function), but doesn't seem to occur when the switching is done in multiple cells of a notebook.

Complete, minimal, self-contained example code that reproduces the issue

import panel as pn
pn.extension()

dummy_button = pn.widgets.Button(name="dummy", button_type='primary')
dummy_text = pn.widgets.TextAreaInput()
toggle_button = pn.widgets.Button(name="toggle")

def toggle(_):
    dummy_button.disabled = True
    dummy_text.disabled = True
    dummy_button.disabled = False
    dummy_text.disabled = False

toggle_button.on_click(toggle)

layout = pn.Column(dummy_button, dummy_text, toggle_button)
layout.servable()
