   * We had to use `max-width` instead of `width` here because of a bug on Firefox
   * that causes a horizontal scrollbar when there is a vertical scrollbar on Linux.
   * This is not a problem on platforms that have a floating scrollbar that doesn't
   * take additional space, but on platforms that we don't have floating scrollbar,
   * it takes some space from the body element and causes horizontal scrollbar to appear.
   * See: https://bugzilla.mozilla.org/show_bug.cgi?id=1400279
