comment_text in 2.5

I was testing a theme out in the new version of WP and found that for some reason my comments appear misaligned. I check the source code and found that instead of the usual <p>comment</p>, the comments are now wrapped in <div style="padding: 1em"></div>, apparently by default. Is it by default and is there a way to bypass this?

Personally, I find it really annoying that I can’t control the styling of this anymore…
