Config continuation_indent not accepting 0

[Cooldude2606]

I am using CodeStyle as part of LuaLS in vscode Lua (v3.10.6) on windows 10 with no other extensions enabled.

I am wanting continuation_indent.in_expr = 0 to disable this rule, however it reverts to the default of 4.
It is not clear why a value of 0 does not work, and there does not appear to be any other way to disable it.
The same applies to continuation_indent and .in_table and .before_block

Here is the .luarc.json being used.
Below is the editor config and lua code being tested:

# see https://github.com/CppCXY/EmmyLuaCodeStyle
[*.lua]

continuation_indent.in_expr = 0
continuation_indent.in_table = 4
continuation_indent.before_block = 4

local function new_something(tbl)
    return tbl
end

local foo =
new_something {
    bar = 1
}

This image shows how the value has reverted back to the default of 4.

This image shows how setting it to any other value such as continuation_indent.in_expr = 7 works fine:

Because I use std::size_t extensively as a data type, I treat 0 as the usual invalid value. Therefore, indentation usually cannot be set to 0

Is there an alternative way of disabling a specific indentation rule?

Currently not available, I might implement it in the future as I am busy with my own language server implementation.
