Can't Fly When Dead in Dead-Flight Zones with Dragonflight Active

I had dragonflight active. I was leveling and in Spires of Arak. My Mage died. I appeared at the spirit healer on a flying mount as a ghost. When I tried to take off, I floated up about 20 feet but could not fly. I just floated back down to the ground. I tried switching to classic flight, but it told me that I couldn’t do that while dead. I had to ride on the ground on a flying mount to my corpse, which isn’t the most fun thing to do in Spires of Arak.
