can't construct core::Optional from rvalue with deleted copy constructor

[dnsge]

Minimum example:

class X {
public:
    X(int);

    static Optional<X> Make();

    X(const X&) = delete;
    X& operator=(const X&) = delete;
    X(X&&) noexcept = default;
    X& operator=(X&&) noexcept = default;
};

Optional<X> X::Make() {
    return X{1};
}

Compilation error:
