   Copy and paste the snippet below into your HTML.

   Note: This cartridge's settings do not allow embedded playback. A [Play at lexaloffle] link will be included instead.

   <iframe src="https://www.lexaloffle.com/bbs/widget.php?pid=wadajugupi" allowfullscreen width="621" height="513" style="border:none; overflow:hidden"></iframe>
   
   
4. Type save @url
5. Copy the URL in the browser and open in a new tab. (URL in my case)
6. Observe that the map data is missing (code and sprites are not missing)

Expected result

In 6, I expect the map data to be present like in the original cartridge and in step 3.
