Audio Random Container window throws a NullReferenceException if docked when editing a script

--

-

*Steps to reproduce:*
# Create and open an empty project.
# Create a C# script (Assets > Create > C# Script).
# Open the C# script in any code editor (to edit later).
# Create an Audio Random Container (abbr. ARC) (Assets > Create > Audio > Audio Random Container).
# Open the ARC asset by double-clicking on it. Make sure the ARC window is closed before opening it.
# Dock the ARC window. Make sure that the ARC asset is highlighted in the Project window, so that it is showing in the ARC window.
# Edit the C# script in any way you please.
# Switch back to Unity with cmd+tab / ctrl+tab. This is to make sure the ARC window keeps showing the asset.
# If no error appears in the console, repeat steps 5-8 until it does. Try to dock the window in various docking areas.

*Actual results:* A null reference error is thrown in the console

*Expected results:* No error is thrown in the console

*Reproducible with versions:* 2023.2.8f1, 2023.3.0b8

*Can’t test with versions:* 2022.3.X, 2021.3.X

*Tested on (OS):* MacOS (M1) Ventura 13.6.4
