villas,
You are trying to fly straight with wing down so the computers will try to correct that by use of spoilers, aileron and rudder. When you are try to do something that is against the design concept the result cannot be predicted.
This Airbus produced document doesn't agree with you.

"With higher crosswind (typically above 15 kt to 20 kt crosswind component), a safe crosswind landing requires:
•
− A crabbed-approach, and
− A partial decrab prior to touchdown, using a combination of bank angle and crab angle (achieved by applying cross-controls).
On most Airbus models, this requires touching down with:
− Maximum 5 degrees of crab angle, and
− Maximum 5 degrees of bank angle."
