If I make a header in an article
# Example Heading
I can make a link to that heading in the same article
[link to example heading](#example-heading)
This generates a URL for the link that jumps to that heading
https://exampleblog.com/example-post#example-heading
However, in the preview for the article in the feed of the blog, the URL becomes
https://exampleblog.com/#example-heading
which is maybe fine as long as your heading isn’t below the <!--more--> tag in your article because then it would not render in the preview. A more consistent behavior, I would think, would be to link to the page for the actual post.
