Windows get messed up due to ARC
If the ARC window is open, it can mess up other editor windows through a certain set of actions. For example, the scene view is blank and shows a black bar at the top.
*Repro*
# Open an empty project
# Create an ARC
# Open the ARC window
# Dock the ARC window next to the scene view
# Import a clip
# Add the clip to the ARC's audio clips list
# Unfold the audio clips list
# Click on the Scene view tab
# Click on a game object in the Hierarchy
# Click on the ARC window tab
# Click on the Scene view tab
Expected: The scene view shows the scene as normal and the ARC window shows its empty state with a button to create an ARC
Actual: The scene view is blank and shows a black bar at the top and the ARC window is blank with no button, throwing an error

Not reproducible in 2023.2.0a17
I suspected [29846|https://github.cds.internal.unity3d.com/unity/unity/pull/29846] but couldn't reproduce it on that one
