Facebook Share – Thumbnail doesn't refresh if you edit post images

Has anybody noticed that if you use a Facebook Share button inside of a post/page it works fine generating a thumbnail.

However, when you go and modify the post by replacing the old images with new images and then try to share again- the functionality is totally broken?

It tries to still post the old thumbnails from the first time you saved the post/page. If you go and delete those images from the Media Library, (hoping that would force it to pull the newly added photos)- it won’t even show anything.
