Addari theme: long site names formats header badly

My website has a slightly above average site name length, which results in Firefox displaying the header incorrectly (see attachment, pdo1).

The solution is quite easy (see 2nd attachment, pdo2). In addari/styles.css, change the #hleft #titles width from 350px to 450px. I can not see any disadvantage in doing this, except if the site logo is too wide.
