NetworkManager resets regulatory domain to incorrect value

[Ken Sharp]

I have added COUNTRY=GB to /etc/default/crda. During boot the RD is correctly set:

But when the interface is associated it is incorrectly reset:

Now, if I HUP wpa_supplicant then it correctly sets the RD again:

But now I'm not associated with the AP.

I tried adding "iw reg set GB" to the "start" area of /etc/network/if-up.d/wpasupplicant but that didn't work. I may have put it in the incorrect place though.
I can't find an NM configuration that overrides the default file.

Is there something wrong with a script somewhere?

At this moment in time I am unaware of a workaround. I'll probably have to remove NM as usual.
