20.04 does not remember preferred bluetooth headset microphone

[Aaron Whitehouse]

In Gnome's sound settings, it takes a sensible approach for my Bluetooth headset speaker:
1) I set it as my preferred audio Output Device
2) I turn the headset off and it disappears, reverting to the built in speakers
3) I turn the headset on again and it switches back to using the Bluetooth headset speaker

This sensible approach is not taken for the microphone. The same flow for the microphone is:
1) Set the headset microphone as the default
2) Turn the headset off and it reverts to the internal microphone
3) Turn the headset back on and it stays as the internal microphone

I have attached screenshots in case they help explain.
