Replicable as in "when dying, the player does not receive the attribtue update the regain their movement speed

[Budderman18]

this seems to effect other potion effects too, dying with strength makes it so you cant attack anything without at least a stone sword

Until this is fixed either by Paper or upstream, I have made a simple plugin to work around the issue.

Well this not happen in upstream for what i check.
In upstream this seems to fix the issue https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/cdd05bc7faac70a5341ce9cd6524ac2ed0a80651#nms-patches%2Fnet%2Fminecraft%2Fworld%2Fentity%2FEntityLiving.patch but just for future effects if you still has a effect use this and die the effect its not removed unless you give the same effect again.

Yes, we're pending an upstream merge
