Dying when moving too fast deletes all visible items.

I noticed this in my realm: if a player uses an elytra and dies by flying too fast into a wall (particularly with a firework boost) all visible items are not dropped. Eg. armor, mainhand, and offhand. Another time I noticed this was if I rode in a boat on ice with a hostile enemy in the back, and it killed me. This has been going on for a long while; since at least 1.19 (3 years!).
