Page.captureScreenshot partial page screenshot

[bmikkelsen22]

I am using the chrome devtools protocol to capture a screenshot of part of a page. In the documentation, there is an optional clip parameter listed for the Page.captureScreenshot call, which is supposed to only take a screenshot of the specified part of the page.

However, even when I pass a value for the clip parameter, the entire page's screenshot is returned.

Is this an issue with my code/understanding of the documentation, or could this be an error? I am using chrome beta 61 by the way.

Here's my code:

Thanks!
