 Here's an image element doing the same thing

 {{{
 <!DOCTYPE html>

 body {background-color: white; color: black;}
 </style>
 </head>
 <body>
 <img id="image" width=0 height=0></img>
 <button onClick="goFS()">click me to go full screen</button>
 <script>
 function goFS() {
         if (document.mozFullScreenEnabled) {
                 let element = document.getElementById("image");
                 element.mozRequestFullScreen();
         };
 }
 </script>
 </body>
 </html>
 }}}
