.opts does not work with param.rx objects

[LecrisUT]

Specifically, as clone=False (like dict.update interface) does not work. Here is a MWE:

import holoviews
import param

holoviews.extension("bokeh")

# Not using `param.rx`, everything works fine
# layout = holoviews.Layout()
# overlay = holoviews.Overlay()
layout = param.rx(holoviews.Layout())
overlay = param.rx(holoviews.Overlay())

overlay *= holoviews.Curve([0, 1, 2], label="One curve")
overlay *= holoviews.Curve([2, 1, 0], label="Other curve")

# This does not work with `param.rx`
# overlay.opts(xlabel="xlabel here")
# This does work though which can be a workaround
overlay = overlay.opts(ylabel="ylabel here")

layout += overlay

# But this is needed, and it does not work because of the previous issue
layout[0,0].opts(show_legend=False)

layout
