Preserve Custom Bottle Names in Potion Brewing

When renaming bottles or water bottles on an anvil in Minecraft, their custom names are lost after brewing potions, reverting to default names like "Potion of Weakness." It would be great if the game preserved the custom names applied to bottles, even after brewing or upgrading potions. This way, players wouldn't have to spend additional experience points renaming the bottle after brewing, keeping the custom names intact throughout the brewing process.
