I'm using Microsoft Edge version 107.0.1418.56 and I'm noticing it adds a couple of margin rules to just about any text element. Here's an unstyled <h2> as an example. See how there's a little bit of top and bottom margin?

Just to double-check I opened the styles tab and yes, the "user agent stylesheet" added a couple of rules.

I'm wondering if these rules should be added to normalize. If so, I'd be happy to create a PR.
