It is. I already mentioned it in the Bugzilla thread and that's
what the patch series I submitted the other day fixes:

Hans de Goede gave it a Reviewed-by, but it has been ignored even
since.
Keep in mind that I'm an occasional contributor and I can barely use
a mailing list,
but this goes back to the patch that Zijun Hu sent back in July and I
was pinged.
I took a look back then, it looked suspect, but I imagined you guys
knew what you were
doing. Fast-forward three months and the code arrives at most
mainstream distros.
Every single cheap Bluetooth dongle on Earth broke again. Just like
that.

I just came across this thread archive by pure chance, this isn't
very user friendly.
Please CC me if you talk about this, I'm not subscribed to any list.
In case it helps any, I have applied Swyter's patch referenced at
comment #243 of the bug referenced above, and it does restore function
to my particular dongle (Gentoo linux, with gentoo-sources kernel
6.0.6.) (I believe I provided the git bisect quoted at the top of this
message.)
