Fyi, military pilot here, there are a handful of mil aircraft that can reverse thrust in flight. A great too for dropping down fast to avoid low/slow flight over hostile areas. There might be a relationship between that ability and this problem.

Also, as I recall, Concorde could do this too...

It can be crazy dangerous. Once a big plane is dropping like a rock, getting back into a climb is very difficult.
