What happens to a person who is scattered to the astral plane when inside of a destroyed bag of holding

When a bag of holding is destroyed, the contents are scattered in the astral plane. If a person is inside the bag, what happens to their body? According to the accepted answer here: “Will loot you find on the astral plane while using astral projection remain when you leave it?” – you don’t have a physical form in the astral plane. Is their body gone, forever? Or do they get a new body when they enter a physical plane?
