I wonder if this relates to a different bug where modifying the generic.max_health attribute in a certain way really fast and giving the player instant damage could cause the player to "die", get a fake respawn screen, and get stuck in the death animation. This is MC-19690 I am mentioning if that helps.
I can confirm it still exists 20w22a.
A good workaround for now is using a modifier instead of setting the base. Modifiers seem to work for generic.movement_speed.
I have Intel UHD Graphics 617 and the game is barely playable for me.
