That is now exactly what I am afraid about, when spoilers are active during a turn (roll) they disrupt the airflow to reduce lift on that side. When this disruptive airflow starts to rotate towards the backside of a spoiler (due to wingfoil) and lifts it up and into a locked position. So far only Airbus has had this and they have a exclusive wingshape (foil). So it has not (yet) been confirmed, but I am a litte afraid it would be possible.
Can I ask where your information is coming from that this has been an issue with Airbus aircraft? I agree with your description of how asymmetric spoiler deployment is used to provide/enhance rolling moments in some aircraft designs, but your assertion that the disrupted airflow can roll back and push a spoiler up doesn't sound right. Can you reference any specific reports, examples, or technical data that describes this phenomenon, or are you just guessing?
If this would be studied with a tailwind then I have no idea what will come out. (windtunnel vision)
I really think you are misunderstanding what a "tailwind" means with respect to the airflow flowing over a wing. An aircraft in flight - even in a "tailwind" - is still always
moving forward through a mass of air, and the air is always
flowing from the front to the back of the wing.
For an aircraft in flight, a tailwind dows not
mean that the airflow reverses and flows from the back toward the front of the wing; it only means that the overall mass of air is moving in generally the same direction as the aircraft, but regardless: the aircraft is still moving forward through that moving mass of air. So in flight, aerodynamically, a tailwind doesn't make any difference in the airflow over the wing at all.
(This is all for an aircraft in flight. In ground operations, i.e. taxiing, you can certainly have wind and airflow in any direction over the aircraft.)
