Jeez, I made this point somewhere at the start of this discussion, but I guess I'll make it again: To resolve this question, the rules would need to specify what order to resolve ending wildshape vs dying outright when you are reduced to 0 hp. It is patently obvious that the rules don't provide that information, if you think they do then you have fooled yourself. So strictly by the book, there is no answer and the DM just needs to decide.
Now Sage Advice has officially resolved that ambiguity. There really isn't any more to say about it, is there?
