Possible Solution:
CSS:

.choices__list--dropdown {
  height: 0; /* added this */
}

JS:

_proto.show = function show() {
    this.element.classList.add(this.classNames.activeState);
    this.element.style.height = 'auto' // added this
    this.element.setAttribute('aria-expanded', 'true');
    this.isActive = true;
    return this;
  }
_proto.hide = function hide() {
    this.element.classList.remove(this.classNames.activeState);
    this.element.style.height = '0' // added this
    this.element.setAttribute('aria-expanded', 'false');
    this.isActive = false;
    return this;
  };

Another possible solution via only CSS:

.choices__list--dropdown {
  height: 0;
}

.choices__list--dropdown.is-active {
  height: auto;
}
