We use tea in our "Summer Pilsner", what we do is steep the bags in our strike water and pour it all in the tun when ready bags and all, doesn't affect the runoff whatsoever. In other words the tea "flavor" is in the wort from beginning to finish. I'm not sure what passion tea has in it but we use Earl Grey. It is a fine beer.
