If I enter a link to the documentation, I see the documentation heading in the preview. But after finishing the post, only the URL of the link is shown. I think, the heading should also be shown in the post.
If you look at your screenshot it shows an error for the docs, that it can’t generate a preview.
There is probably a technical reason, my guess is that the wiki software does not add open graph meta tags to the html, so the “preview” feature does not work properly.
Unfortunately I fear changing this is not easily possible as both the forum and the wiki use off the shelf software with minimal customization.
Thanks for the feedback. I was wondering: The forum detects the heading (shown in preview) - so I expected that the heading was shown in final post too (without hints concerning missing open graph meta tags).
If I insert a link to
the behaviour is the same (I did not add any open graph meta tags).
