Pod Bay bug, or SE chat feature by design?

I don't think the pod bay has a "meta" so I'll try to ask here?

I dropped this link into the pod bay, hoping to see the link in blue font. Instead I got a vanity picture of Matt Damon and a summary of a Wikipedia article.

The stackexchange chat function overrode my link and plopped a big thing in its place that I didn't want there. Is this a chat-bug or a chat-feature by design?

https://en.wikipedia.org/wiki/Matt_Damon#Early_years:_1988.E2.80.931996

But all I got is this lousy photo:

Please do not add the bug tag to my question! It attracts people who come and zero-out the question by adding the by-design tag. I do not know if this is a bug yet or not, this is why I'm asking the question.

I'm not prepared yet for the by-design tag-putters!

• It's not a bug. I'd add [status-by-design], but I suspect that won't be welcome. If you want to avoid the onebox effect put something else in the chat item: Look at this: https://en.wikipedia.org/wiki/Matt_Damon#Early_years:_1988.E2.80.931996 Oct 27 '16 at 4:15
• If you click the "Matt Damon" link, it takes you to that exact link. It just turns the link into a preview. Oct 27 '16 at 4:47
• @JonEricson that's exactly the answer I needed, thanks! If you can leave it as such I can accept it and close this off. I or you can also adjust the question if it helps. Movie stars get their mug exposed offen enough. :)

• FWIW, I'm not exactly sure why you would want to avoid this effect, for the reason Phiteros mentioned.

• @called2voyage the link I pasted was a link to a specific sub-section of the article - the part where he drops out of Harvard. I was hoping for just a one-line link, not a big block of irrelevant text and a mug shot of a movie star. I didn't realize that if you include the link with text it shows as a normal style link, but if you don't type some stuff, it will summon an unwanted/unexpected banner and photo. Imagine every time you want to add a link to a subsection of some text a UI decides to put a giant banner and photo.

• @JonEricson I've recovered sufficiently, feel free to "by-design" me ;-)

As also mentioned in that comment, if you add something else to the line along with the url that's not interpreted as a part of the url, such as See: url or @user url then you can rest assured that your chat post will remain Matt Damon-free.
