Grindstones do not remove Custom Enchantment name/lore
A custom enchantment that appears in lore text is not removed by grindstones, such as:
Diamond Sword
Sharpness IV
Venomous II
Should lose all entries, but instead currently becomes:
Diamond Sword
Venomous II
The enchantment glint and effects are removed, but the lore-text stating the enchant name remains.
