Inline styling appears to break HTML validation

Hey! Thank you for sharing this fine plugin with the community. It definitely improves privacy, speed and UX a lot.

A little grief. The style tags in the body are considered invalid by the HTML validator. Have a look at https://validator.w3.org/nu/?showsource=yes&showoutline=yes&doc=https%3A%2F%2Foldrup.net%2Fembed-privacy%2F#l304c1674

Would it be possible to enqueue styling in the head, in a file or inlining it, satisfying the validator?

Kind regards

Bjarne
