Overlay after click shown over article text

Hello. When click to approve a video (YouTube, Vimeo), the video container is suddenly expanded and is blocking part of our article text. I tried to apply some quick clear:both rules via Web Inspector, but that doesn’t seem to fix it. It doesn’t seem to happen on Twitter and Instagram embeds, so it probably is related to how videos are displayed.

I have provided an article URL where this effect is visible.
