LuaTable always initializes array to 8 items minimum

[CodeSmile-0000011110110111]

I noticed that new LuaTable(0, 0) still generates an array with 8 entries.

Is there a reason for doing this in the LuaTable ctor?

    public LuaTable(int arrayCapacity, int dictionaryCapacity)
    {
        array = new LuaValue[Math.Max(arrayCapacity, 8)];

I thought I'll report it because I'm not sure whether this is intentional because that amounts to roughly 100 bytes overhead for an empty LuaTable.

I noticed because I have a LuaTable Inspector drawer for Unity and it just happened to add eight "null" entries to the previously empty Array:

For this I can easily work around it by not serializing "nil" values rather than defaulting them to 0.

I noticed this was actually added to v0.5. Main branch doesn't have the default 8 items.
