Progress, and some bad news... Testing with Sony WH-1000XM3 I can reproduce the bug easily. But it's not a recent regression if at all. The same bug occurs in an original Ubuntu 18.04 install without any updates.
I'm tempted to clarify that Sony WH-1000XM3 is our main test case here. Any future fix might benefit multiple different models, but it seems the WH-1000XM3 is presently very popular and is what the original reporter(s) of three quarters of these bug reports are using.
