Video lightbox

Hi. I’m trying to use the video lightbox feature in Elementor 1.3.3. Everything looks good in the backend, but when I load the page, I’m always getting “padding-top: 56.2393%” above the image, out of nowhere.

I’ve tried it on several pages, and I still get this exact padding-top of 56.2393%.

<div class="elementor-wrapper elementor-open-lightbox">
<div class="fluid-width-video-wrapper" style="padding-top: 56.2393%;">
<iframe src="https://www.youtube.com/embed/9uOETcuFjbE?feature=oembed&rel=0&controls=1&showinfo=0&wmode=opaque" allowfullscreen="" id="fitvid819742" frameborder="0"></iframe></div>
<div class="elementor-custom-embed-image-overlay"><img src="http://example.com/assets/intro-video-homepage.jpg">
<div class="elementor-custom-embed-play"><i class="fa fa-play-circle"></i></div>
</div>
</div>

Any ideas?
Thank you in advance.
