Battlegrounds deathrattle/reborn interaction

I’m not even sure if this is a bug or not and ive only noticed the interaction in latest patch
but deathrattles and reborn seem to interact differently if you add additional deathrattles to a minion
it always seems to activate the first deathrattle then it reborns and then the extra deathrattles go off
i have no idea why it is this way and if its a bug or not but i thought it was ment to be all deathrattles then reborn
