In some arena matches, there are too many arena frames displaying. Eg, in a 3v3 match there will be 4 arena frames. Happens primarily (maybe only?) when the opposing team has at least one pet class. One of their teams' pets is applied as a minion of a 4th arena enemy. Looks like a blizzard bug, but maybe we can find a fix without causing interface taint.

Haven't run into this issue for a long time. Closing for now.
