What if I cooked a covered pan of chicken in the oven while baking challah at the same time?

I cooked a covered pan of chicken in the oven  and I baked Challah in the oven at the same   time. What is the status of that Challah?  In this case, the Challah remains Pareve,   provided that the oven was a Pareve oven and the  chicken was covered, then we say the steam from   the chicken will stay inside the pan, and the  oven remains Pareve, and therefore the Challah   remains Pareve. However, if foil comes off the  pan, the steam would come out of the chicken and   would get absorbed into the Challah, and the  Challah should then not be served with dairy.
