    // so we're just doing this for now instead. 
    //
    // Implications of this hack: for the first second after mounting this component, a user opening
    // this component will have it open on the left side of the screen instead of the right side. Then,
    // when this timeout triggers, the sidebar will close. Reopening it will open it on the right side
    // of the screen.
    //
    // It's also possible some slow computers/internets might have issues that would require longer than
    // one second of waiting, but in that case we just default to opening this sidenav on the left side
    // of the screen (default sidenav behavior) instead of the right side.
