intelephense.diagnostics.typeErrors does not appear to work

[esetnik]

intelephense.diagnostics.typeErrors: Enables diagnostics on type compatibility of arguments, property assignments, and return statements where types have been declared, default: true

In the following sample code no diagnostic error is generated:

    public function test(string $arg): int
    {
        return 'test';
    }

Hi, I have confirmed it. it will be reproduced. It seems to be a problem on the language server side.
