[MC-260436] Item Tags in 1.19.4-pre1 have extra entries

Some examples:

wooden_doors.json

{
  "values": [
    "minecraft:oak_door",
    "minecraft:spruce_door",
    "minecraft:birch_door",
    "minecraft:jungle_door",
    "minecraft:acacia_door",
    "minecraft:dark_oak_door",
    "minecraft:crimson_door",
    "minecraft:warped_door",
    "minecraft:mangrove_door",
    "minecraft:oak_door",
    "minecraft:spruce_door",
    "minecraft:birch_door",
    "minecraft:jungle_door",
    "minecraft:acacia_door",
    "minecraft:dark_oak_door",
    "minecraft:crimson_door",
    "minecraft:warped_door",
    "minecraft:mangrove_door"
  ]
}

sand.json

{
  "values": [
    "minecraft:sand",
    "minecraft:red_sand",
    "minecraft:sand",
    "minecraft:red_sand"
  ]
}

This only happens with block items, leading me to believe the issue is present with adding blocks, or anything with the ItemLike interface, as entries to item tags.
