$post object passed to clean_post_cache action can contain outdated values

[tabrisrp]

This occurs when publishing or deleting a post.

In the clean_post_cache() function, get_post( $post ) is called and assigned to $post.

At that moment, the value of the $post parameter post_status = draft if publishing, publish if deleting the post.

There is then a call to wp_cache_delete( $post->ID, 'post_meta' );, which correctly updates the value of post_status, if you perform another get_post() right after.

But, the $post object is then passed to the action clean_post_cache, with the outdated values instead.

So if someone hooks a function on clean_post_cache, and uses the $post object passed, it's going to receive incorrect values compared to what would be expected. But if you perform a get_post() inside that function, you will get the correct values.

I only tested this with the post_status parameter, but this might be affecting others too.

I would expect that the $post object passed to the clean_post_cache action contains up-to-date values.
