Observables being deepcopied

[vladdez]

Passing observable string throws an error when used with show_sortval

obs = Observable(data)
chan_i = Observable(1)
sort_val = Observable(evts_e.Δlatency)
str = @lift("ERP image: channel " * string($chan_i))
f = plot_erpimage(times, dat_e; sortvalues = sort_val, show_sortval = true, axis = (; title = str))
str[] = 5

on the line sub_config2 = deepcopy(config)

It seems it doesn't like Observables being deepcopied. Any ideas how to solve it?

I guess it doesnt make much sense to deepcopy an observable, because you'd break the realtionship to the original observable?

why/where exactly do we deepcopy the config?

Why not generate a new config there and fill in the kwargs again?
