get_post_thumbnail_id doesn't work in post preview

[nightcoder]

The code returns the page/page's featured image id for all additional loops in the preview mode.

get_post_thumbnail_id( $post->ID )

It is pretty obvious when you click previewing a WooCommerce product, the "Related Products" thumbnails, WooCommerce related widgets, all of them will display the post's thumbnail.

If you remove the

_thumbnail_id=

part of the preview url, it works properly.
