"wieldview" does not support changes to textures via metadata

[skylord-at-hub]

Wielded items in third person does not update after the texture has been updated via metadata.
You can test youself using the command Im providing below:
Notice: This command assumes you are testing on minetest_game

core.register_chatcommand("change_sprite", {
    description = "change texture of existing item to diamond sword",

    func = function(name, param)
        local player = core.get_player_by_name(name)
        local stack = ItemStack(player:get_wielded_item())

        if not player or stack:is_empty() then
            return false, "You arent real or your not holding an item"
        end

        local meta = stack:get_meta()
        meta:set_string("inventory_image", "default_tool_diamondsword.png")
        meta:set_string("wield_image", "default_tool_diamondsword.png")
        player:set_wielded_item(stack)
        return true, "Success! Changed texture to diamond sword"
    end,
})

Press the "Toggle camera" button (c by default) until you are in 3rd person. You will notice that you arent holding a diamond sword (even though the textures have been changed)
