When using the homepage to display the latest posts (set in Settings → Reading). the og:image of the homepage is incorrect. It uses the og:image of the latest post, instead of the one set for the frontpage in SEO → Social → Facebook

Please describe what you expected to happen and why.

I expected the homepage to use the image set for in SEO → Social → Facebook → Frontpage settings

How can we reproduce this behavior?

1. Set an image in SEO → Social → Facebook → Frontpage settings
2. Set a different image for your latest post
3. Set the homepage to show the latest posts in Settings → Reading
4. Check the source of the homepage, it will show the og:image of the latest post

It does not seem to happen to everybody, so there must be something else triggering this issue.
