It took me so long to understand what this is about, so, for other unaware reviewers: This is about showing a preview of links posted in Talk, like what is done when posting links on other chat platforms.

And this is the backend part, is not specific to Talk, and may not be specific to links in the future, which is what makes the original description convoluted.

Sorry, should have clarified that a bit more, but I've taken your description for the first post in addition
