This would be quite an awful sight.
I bet the passengers were terrified, thinking is this contagious etc.
I flew many times to and from Jeddah, every year during Mecca, Hajj, you'd expect a passenger to die (rediculous religion forcing these elderly people to attend), most deaths were silent, passing in the toilet. Very old people, probably never flown or traveled before in their life.
Before landing the flight attendants would knock on the toilet door, no answer, look inside then lock the door, the plane would land.
Abu Dhabi was an issue because your connecting flight to BKK would be delayed for a few hours.
