Broken Wheel Button Logic

[nworb-cire]

Describe the bug

Sometime since the opendbc migration, GM's steering wheel button logic has become broken. The resume button is now functionally equivalent to the set button. By this I mean that it will always cause the speed to be set to max(65 if experimental else 25, vEgo) instead of the previous set point as is desired.

Which car does this affect?

Chevrolet Volt 2018

Additional info

I have confirmed with a few other GM users that they experience this bug on master(-ci). You can see in the first segment of this route the broken behavior.

(Note: dirty git required to remove my car from dashcam mode)

Not GM specific, just had this on my Golf.

@sshane seems to be this: #33693. It now waits for a loopback on the enabled, and there's no more buttonEvents.
