    // To allow this, MUI buttons provide an `autoFocus` prop. However, while
    // the button does get auto focused, it doesn't show the visual
    // focus-visible state until the user does an keyboard action.
    //
    // Below is the current best workaround to get the focused button to also
    // show the focus-visible state. It uses the onEnter callback of the
    // transition to focus on the ref to the auto focused button (if any).
