The ARC tab becomes unresponsive when docking the ARC window after deleting an asset that was showing in the ARC window. The tab is inaccessible if docked next to another tab and it becomes black if if is the only tab in the window.

*Regression details*

I can reproduce this on 2023.2.0b16 but not on 2023.2.0b10 so the bug was introduced somewhere between those versions.

*Repro*
# Create an ARC asset (Assets > Create > Audio > Audio Random Container).
# Open the ARC asset so that it shows in the ARC window.
# Delete the ARC asset. The ARC window should now show its day0 state.
# Drag the ARC tab and dock it somewhere in the Editor.

Expected: The ARC window acts as normal and shows its day0 state.

Actual: The ARC window becomes unresponsive rendering black if it's the only tab in the window.

Throws multiple times initially but then stops complaining.
