I have the following code.

```
 <html>
     <body>
      <div>
        <iframe> 
          <html>
           <body>
                content
           </body>
         </html>
        </iframe>
      </div>
     </body>
    </html>

```

I want to show wait cursor until the content of the iframe is fully loaded.
I have control over both the html.
