Big space when setting a preview image

Hello,
If I set a preview image I get a huge spacing issue between the top of the widget and the video itself. However if I remove the preview image, the spacing is perfect.

I’m guessing this might be a CSS issue but im not sure where to begin on that.
Thank you so much, this is a fantastic widget!
