For example when the topic was `constructible polygon` I post a link to `https://en.wikipedia.org/wiki/Constructible_polygon` then the oneboxing looks nice and very useful.
> **[Constructible polygon](https://en.wikipedia.org/wiki/Constructible_polygon)**

> In mathematics, a constructible polygon is a regular polygon that can be constructed with compass and straightedge. For example, a regular pentagon is constructible with compass and straightedge while a regular heptagon is not. There are infinitely many constructible polygons, but only 31 with an odd number of sides are known.
> Some regular polygons are easy to construct with compass and straightedge; others are not. The ancient Greek mathematicians knew how to construct a regular polygon with 3,...
In above case, the onebox has a lot of value.
However, if the topic was about about something more specific such as `Compass and straightedge constructions` which requires an anchored link, the adding a link to `https://en.wikipedia.org/wiki/Constructible_polygon#Compass_and_straightedge_constructions` is much less useful.
Could this be improved somehow?
Ideas:
- When `#` is in the link, ask the user if a onebox should be generated while typing?
- Drop the generic image from `og:image` meta tag?
- Add an image form that specific (wiki) chapter contained in the `#` anchored link, if any?
- Add the title of the (wiki) specific chapter instead of the title of the (wiki) page (`og:title`)?

I think we have special handling for the Wikipedia ones that do link to the anchors?

Though looking at it, the image does appear to be the same, but it picks up the chapter title and paragraph.

The following link doesn’t work as expected with oneboxing for example:
`https://www.whonix.org/wiki/Onion_Services#cite_note-11`
> **[Onion Services](https://www.whonix.org/wiki/Onion_Services#cite_note-11)**
>
> Install package(s) libapache2-mod-removeip following these instructions: | Anonymously host any server with Whonix and Tor onion services

Interesting. I am surprised by that. So I didn’t choose my example wisely. 🙂
It works for wikimedia (which is based on mediawiki) but doesn’t seem to work for other websites based on mediawiki or other websites with anchors?

I think this was improved in [FEATURE: Enhance onebox descriptions with URL fragment/anchor context by IanButterworth · Pull Request #36536 · discourse/discourse · GitHub](https://github.com/discourse/discourse/pull/36536)
Your example `https://www.whonix.org/wiki/Onion_Services#cite_note-11` now looks like this:
> **[Onion Services](https://www.whonix.org/wiki/Onion_Services#cite_note-11)**
>
> Install package(s) libapache2-mod-removeip following these instructions: | Anonymously host any server with Whonix and Tor onion services
Without the anchor it’s still
