If you link to an answer with just a link it'll get expanded in the inline preview (as such the below is just https://stackoverflow.com/q/28508017/124486
getting expanded to the title of the question),
However if you try to stylize it, such like this (which looks at least 9,000 times more professional)...
* _"https://stackoverflow.com/q/28508017/124486"_
As this,
- "https://stackoverflow.com/q/28508017/124486"
Then in the editor preview it will look kosher (just [edit] this post to see what the in-line rendering displays), which means JavaScript is doing its job rendering the Markdown content properly.
The real problem here seems to be the server-side rendering with C#. When stylized, the URL is no longer expanded to the title of the question. I have reason to believe they're still on the shareware library version and that they'll have to upgrade it so the community can enjoy the enterprise level Markdown rendering we need.
Can't edit the question with the link above to see it?
This is what it looks like in the editor preview:
