 * until to the next tick, similar to `setTimeout` with a timeout of `0`.

   * For length is intended the main axis relative to the placement of the popper.<br />
   * This means that if the placement is `top` or `bottom`, the length will be the
   * `width`. In case of `left` or `right`, it will be the `height`.
   *
   * You can provide a single value (as `Number` or `String`), or a pair of values
   * as `String` divided by a comma or one (or more) white spaces.<br />
   * The latter is a deprecated method because it leads to confusion and will be
   * removed in v2.<br />
   * Additionally, it accepts additions and subtractions between different units.
   * Note that multiplications and divisions aren't supported.
   *
   * Valid examples are:
   * ```
   * 10
   * '10%'
   * '10, 10'
   * '10%, 10'
   * '10 + 10%'
   * '10 - 5vh + 3%'
   * '-10px + 5vh, 5px - 6%'
   * ```
