Despite the automatically hyperlinkified URI having enough space around it (one line) to be a block element, it doesn’t oneboxify, since:
```Markdown
1. Text
https://example.com
Text
```
…becomes:
* * *
1. Text
* * *

Try rebuilding the HTML of the post once — that often fixes issues where links don’t onebox properly:

I think the spaces in front of it would make it an inline onebox and not a full one. I’m not sure I know a workaround. 🤔

Did that work for you?

@JammyDodger, that’s what I see at every instance I’ve tried thus far (about 8, in total).

@janan\_gagan, I don’t possess TL4 permission anywhere… If any of you are able to rebuild the HTML5 content of my post at `/1`, that would confirm whether it works. However, per the aforementioned, I’m doubtful.
In the meantime, I’ve converted this to a #Contribute > Feature post, since it appears to currently be impossible.
Thanks, regardless.

Yes, there’s a [specific logic in our markdown-it tokens](https://github.com/discourse/discourse/blob/main/app/assets/javascripts/discourse-markdown-it/src/features/onebox.js#L38-L54) that forces links to be considered **inline** oneboxes in cases that are not top level links (ie. not inside any list/blockquote/etc)

@renato, they can still oneboxify inside ``, though. Seems especially strange to permit that, but not any other block element. What’s the rationale?

There’s no explicit rationale, it’s just that raw HTML is seen by markdown-it in a flat way, it doesn’t try to infer the nesting from tags being opened/closed.

@renato, seems to me that, insofar as the CSS defines the element that encapsulates a URI as a block element, oneboxification should occur; I can’t think of any problematic edge cases.
