AudioSource starts playing at full volume when AudioMixerGroup is unloaded

If the AudioMixer is removed the AudioSource will revert to outputting through the listener - depending on the settings of the mixer vs AudioSource/Listener this could indeed sound like a jump in volume. this is expected.
How to reproduce:
1. Open the “bug-audiomixer-destroyed.zip“ project
2. Open the Addressables Groups window (Window > Asset Management > Addressables > Groups)
3. Select "Use Existing Build" in "Play Mode Script" in the Addressables Groups window
4. Build the Addressables (Build > New Build > Default BuildScript)
5. Open the “AudioScene“ Scene
6. Enter Play Mode
7. Observe the audio volume in the Game view
8. Click the "Unload Audio Mixer Group" button in the Game view
9. Observe the audio volume in the Game view
Expected result: The audio continues playing at the previously observed volume
Actual result: The audio starts playing at full volume
