There's something unique to WordPress.com that's causing this behavior, because when I apply this patch to a different test site, I get extra spacing between the buttons:

The markup hasn't changed. I'll keep digging and see what the difference is.

Not sure what the difference is, but updating button styles to border-box and updating the padding solves this problem on WP.com without making the spacing wonky on self-hosted installations.

Should I worry about the Theme Check results? Do we usually make updates to older themes to comply or is it safe to let those slide?
