If you enable Edible enchant_golden_apple in the configuration file, you can revive it, and if you enable it, there will be a slow effect after falling, although the player can be revived after eating the enchant_golden_apple, the slow effect will not disappear, unless the player really dies, the effect will disappear

Mod version?
Game version?
Mod loader used?
Version of the mod loader used?
Any configs changed?

Taking another look and trying to decipher the issue, I figured out what you meant.

When the slowness effect is enabled on the config, using food to revive the player does not remove the slowness.
