To clarify, I used this `embed.html` test document:

```
<!DOCTYPE html>
<html>
  <head>
    <title>PromDash iframe test</title>
  </head>
  <body>
    <p>This is a paragraph before the iframe.</p>
    <iframe src="http://localhost:3000/embed/demo-dashboard" style="width: 100%; height: 600px;">
    <p>This is a paragraph after the iframe.</p>
  </body>
</html>
```

When resizing the browser window, the iframe width would change, which would immediately resize+redraw the graph inside it without having to trigger another AngularJS loop.
