Can't style video in rich text block?

I am trying to add a default style the same way that I would any other media type or element but it says no styling is available for this element. I am having an issue with a facebook live video. It is not rendering full height so figured I’d be able to style it just like any other element nested in a rich text block.

This is for a client’s blog that is using CMS.

Here is how the video is being cut off:

I just tested my link on embed.ly and it renders fine: link


Here is my public share link: LINK
