Redactor demo - problem with HTML button

The demo at http://jquery-spellchecker.badsyntax.co/redactor.html appears to break the HTML/Source toolbar button on the redactor toolbar? Tested with latest versions of Chrome, Firefox and ie.

I fixed this by changing the literal name "toggle" to "spelltoggle" (or anything unique) as follows :

      this.addBtn('spellchecker', 'Spellchecker', function(obj) {
        obj.spelltoggle();
      });

    spelltoggle: function() {
      if (!this.spellchecker) {
        this.setBtnActive('spellchecker');
        this.create();
        this.spellchecker.check();
      } else {
        this.setBtnInactive('spellchecker');
        this.spellchecker.destroy();
        this.spellchecker = null;
      }
