It's just your browser's HTML parser. Line 6:

  #                         / <//_\

This is being interpreted as a malformed HTML closing tag, which (according to the HTML5 parsing algorithm published by WHATWG) gets treated as a comment. The file doesn't contain any > past this point. This leaves the uncommented contents from lines 1–6:

  #                               ,:
  #                             ,' |
  #                            /   :
  #                         --'   /
  #                         \/ />/
  #                         /

Or, with whitespace collapsed:

  # ,: # ,' | # / : # --' / # \/ />/ # /

Which should be exactly what you observe.
