`so.Range()` cannot be "overplotted" by an additional mark added with so.Plot.add()

[noboss93]

As far as I understood seaborn.objects correctly, marks that get added later should overplot previous marks. However, it seems like that the so.Range() mark allways stays on top of later added marks.

import seaborn.objects as so

y = range(1,100)
x = range(1,100)

(
    so.Plot(x=x, y=y)
    .add(so.Range(linewidth=5, color="#A20013"), so.Est(errorbar=("pi", 50)), y=[50]*99, orient="y")
    .add(so.Dot(pointsize=30, color="Blue"), so.Agg(func="median"), y=[50]*99, orient="y")
    .add(so.Dot(pointsize=20, color="Green"), so.Agg(func="median"), y=[50]*99, orient="y")

)
