Video embed vertical scrolling

Maybe a bug?

When I embed my video in Gutenberg, there are no scrollbars, but in Fluent Community courses there is a vertical scroll no matter what settings I tweak. Are there unique styles being applied for embedded code?

Here's the code my video host uses:

<div style="position: relative; width: 100%; height: 0px; overflow: hidden; padding-bottom: min(64.21%, 95vh);"><iframe allowfullscreen="" mozallowfullscreen="" webkitallowfullscreen="" playsinline="" allow="autoplay; fullscreen" src=“VIDEO.URL” width="100%" height="100%" style="border: 0px; position: absolute; inset: 0px;"></iframe></div>
