With responsive design. When the header is long, the message (1 new reply) is split when the line breaks. I think it should have its own line. I suggest making a line break in the code.

question_list.php

<br><a href="<?php echo $lastReplyUrl;?>">(<?php echo JText::sprintf('COM_COMMUNITYANSWERS_NEW_POSTS_TEXT', $item->new_posts)?>)</a>
