    Its missing a grouping parens 
    # you need extra (?:)
$tag = qr{</?(?:(?!sup)[^>])*>}i;

      That will also keep <supfoo> and <foosup>. A partial improvement may be 
      $tag = qr{</?(?:(?![< ]sup[ >])[^>])*>}i;

      It works, however I'm not terribly sure about why it works...

    You're right, I updated my regex - should work now.

      It works, but will miss some like < sup > </ sup >, if you add grouping like this it will get them all :)
