I created a new signature today. It aligns well below a post when I reply to something (example: https://chroniclesofelyria.com/forum/topic/17618/academy#post181534) but it spans to 100% width when it is used in the first post of a new topic (example: https://chroniclesofelyria.com/forum/topic/17325/how-see-new-posts-and-replies). It does not look like intended design.
