Applying the patch fixed my problem with my Sony WH-H900N headphones.
Probably a different bug but if I open Sound Settings -> Input and change the input from "Internal Microphone Built-in Audio" to "Headset WH-H900N (h.ear)" the quality degrades and the Output profile changes to "Headset Head Unit (HSP/HFP)". If I change the Output profile back to "High Fidelity Playback (A2DP Sink)" I get high quality audio again but the Input changes back to "Internal Microphone Built-in Audio".
Or is it that you can't use the headset microphone and get high quality audio at the same time?
