Owl Carousel 2 - autoHeight (multiple items)

At the moment the Owl Carousel autoHeight works only with 1 item on screen. Their plan is to calculate all visible items and change height according to highest item. I work around this problem by calling the .active classes on the visible items, and give the invisible items a small height. Is there already a more elegant solution?

HTML

<script src="https://rawgit.com/OwlFonk/OwlCarousel2/develop/src/js/owl.carousel.js"></script>
<div id="bizamajig-gallery-1" class="owl-carousel">
    <div class="item">
        <img src="http://via.placeholder.com/350x150?text=1">
    </div>
    <div class="item">
        <img id="image-2" src="http://via.placeholder.com/350x150?text=2">
    </div>
    <div class="item">
        <img src="http://via.placeholder.com/350x150?text=3">
    </div>

    <div class="item">
        <img src="http://via.placeholder.com/350x150?text=4">
    </div>
</div>
