og:image incorrect when jetpack plugin is enabled

• [x ] I've read and understood the contribution guidelines.

Please give us a description of what happened.

When the jetpack plugin is installed and CDN image option is enabled all images should be served from the CDN domain (wp.com). However the facebook og:image url is not being served from the CDN domain.

Please describe what you expected to happen and why.

I expected the facebook og:image url to be served from CDN domain (wp.com).

How can we reproduce this behavior?

1. Install jetpack plugin and enable CDN image option
2. Install wordpress seo and enable facebook open graph tags
3. Navigate to any page and view the source code and look at og:image
