    REGRESSION(262334 at main): Fix leak of SecurityOrigin with postMessage
    https://bugs.webkit.org/show_bug.cgi?id=268915

    Reviewed by Charlie Wolfe.

    DOMWindow::createTargetOriginForPostMessage could return a new
    SecurityOrigin with two refs.
    It is only used with RefPtr, so we only need to have one ref.
