removing a plot does not update the kpanel

[jmrouet]

k3d python and js version is the same: yes 2.16.0

• K3D version: 2.16.0
• Python version: 3.9.16
• Operating System: windows 11 x64

Description

when removing a plot element with the "plot -= xxx" syntax, the plot object still appears in the K3D Panel

What I Did

in a first cell

plot = k3d.plot()
line = k3d.line([0,0,0,1,0,0], name="test", group="toto")
plot += line
plot.display()

here the line is displayed as expected and toto/test appears in the "objects" section of the panel

then in another cell :

plot -= line

actually removes the line plot, but is is still displayed in the panel on the side.

And if unchecking/checking the "visible" toggle button, the line reappears, so actually the reference to the object still exists somewhere.... is there a leak ?

if I later progammatically hide and show the menu with

plot.menu_visibility = False
plot.menu_visibility = True

then the menu gets updated, but it is not very convenient

@jmrouet good spot. Very likely my silly error in js code. I will fix it.
