Array#includes overload doesn't work on arrays over generic types (`T[]`)

const arr: ('a' | 'b')[] = [];
arr.includes('some string');

function someFn<T extends string>() {
    const arr: T[] = [];
    arr.includes('some string');
    //           ^^^^^^^^^^^^^ Argument of type '"some string"' is not assignable to parameter of type 'T | (WidenLiteral<T> & {})'
}
