It looks like the problem with the scaling. For a page like this
<style>
iframe {
width: 600px;
height: 300px;
transform: scale(0.5);
transform-origin: 0 0;
}
</style>
<body>
<iframe src="http://localhost:8000/site-isolation/resources/green-background.html" frameborder=0></iframe>
</body>
It is expected to render { 300 x 150 } green rectangle for the iframe because its size is { 600 x 300 } and it has transform of scale(0.5). But we end up having { 150 x 75 } green rectangle. So it seems the scaling is applied twice.
