If a review is published without any header text, we still show a

"Comment" button there (where "Reply" would be if the header existed).

In this case, we had a bunch of extra padding around the empty header

element, which was creating a pretty ugly blank space. To fix this, I've

added an extra class in the case that the header text doesn't exist, and

removed the padding for that class.

Published a review with comments but no header text. Saw that the

"Comment" button was now positioned in a reasonable location, rather

than with a ton of whitespace above it.
