777 behaves like this and AFAIK it is something to do with the (big) engine nacelles and thrust/airflow increasing during the early stages of the ground run interacting with the crosswind. Once steady over 60-80kts it reverts to how you think it should work.

As you naturally apply rudder to keep the aircraft tracking straight, and this becomes an almost reflex action, it’s not until you are made aware of this particular phenomenon and think about what your feet are actually doing that it becomes obvious that this is what happens on most occasions.
