Cannot layout Pipeline

[MarcSkovMadsen]

Panel 0.10.3

If I put a Pipeline in a column I see a pn.Param version instead of the pipeline.

import webbrowser
import param
import panel as pn

pipeline = pn.pipeline.Pipeline()

class GetPassword(param.Parameterized):
    password = param.String()

    _panel = param.Parameter(precedence=-1)
    _widgets = {
        "password": pn.widgets.PasswordInput
    }

    def __init__(self, **params):
        super().__init__(**params)

        self._panel = pn.Param(
            self, widgets=self._widgets
        )

    @param.output('password', param.String)
    def panel(self):
        return self._panel

get_admin_password_from_pam = GetPassword
pipeline.add_stage("Get Pam Password", get_admin_password_from_pam)
pn.Column(pipeline).servable()

A Workaround is

pn.Column(pipeline.layout).servable().
