Linked to the post where I ran across this; it should come down to styling or delegating the right html elements to pub titles embedded in comments. Here are a few screen shots:
It appears that the embedded post loaded a full on iframe
<a href="https://hubski.com//pub/252093">Discuss this on Hubski.</a>
Text surrounded by asterisks (*) is italicized.
Text surrounded by plus signs (+) is bolded.
Text surrounded by vertical bars (|) is quoted. If you double-click a paragraph, it will be quoted.
Text surrounded by tildes (~) is blocked out.
Symbols such as *, +, |, and ~ can be used literally by placed a \ in front of the text.
A user's name surrounded by at signs (@) links to their profile, and the user is notified that you mentioned them.
A word surrounded by hash signs (#) becomes a tag and links to posts with that tag.
Text after a blank line that is indented by two or more spaces is reproduced verbatim in a different font.
URLs become links. However, new users cannot post links in comments.
Hubski URLS become embedded cards, displaying information about the post or comment.
Text can link to URLs by using the following format: [linked text](http://theurl.com)
Youtube, Vimeo, Soundcloud, Twitter, and Spotify urls will embed the content automatically.
Image URLs (.png, .tif, .gif, and .jpg) will embed automatically.
Looks like we were missing some styling in the office stylesheet, hopefully it's fixed now (might have to clear your cached css).
I've encountered that some, it's generally when hubski is under heavy load and a refresh generally fixes it. That link loaded fine for me on mobile.
