Description of expected behavior and the observed behavior

In jupyterlab, I'm attempting to update the value of a bokeh pane by setting

self.bokeh_pane.object = bokeh.models.Div(text='Hello world')

It works when self.bokeh_pane is nested in pn.Column but not when nested in pn.Tabs where it proceeds to throw the error: AttributeError: unexpected attribute 'children' to Tabs, possible attributes are active, align, aspect_ratio, background, css_classes, disabled, height, height_policy, js_event_callbacks, js_property_callbacks, margin, max_height, max_width, min_height, min_width, name, sizing_mode, subscribed_events, syncable, tabs, tabs_location, tags, visible, width or width_policy [76]:

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

# This works:
class MVP(param.Parameterized):

    test = param.Selector()
    action = param.Action(lambda x: x.param.trigger('action'), label='Run Query')

    @param.depends('action', watch=True)
    def execute(self):
        print('action!')
        self.bokeh_pane.object = bokeh.models.Div(text='Hello World!')

    def view(self):
        controls = pn.Param(self.param, widgets={
            'action': {'button_type': 'primary'},
        })

        self.bokeh_pane = pn.pane.Bokeh(bokeh.models.Div(text='Hello'))

        return pn.Tabs(
            ('Controls', controls),
            ('Plots', pn.Column(self.bokeh_pane)),
        )

m = MVP()
m.view()

# Changing this line causes it to fail:

        ...
        return pn.Tabs(
            ('Controls', controls),
            ('Plots', self.bokeh_pane),
        )

Thanks so much for creating this amazing plugin. This is not a high priority fix since I've already found a workaround but wanted to contribute this little tidbit in case it's important to you.

Thanks again :)
