@curiosityLynx The name is written out fully automatically when I click "Add comment"; kbin, the instance where I am, will put full identifier automatically. But on posting it only shows the "id name" without "instance part", but links to the account. Like in this situation with your name. My guess is, the person is still tagged correctly and only the HTML link name is shown in the browser.
I just wish it would link to the actual post or reply directly, instead the person. With the ability to preview on mouse hover (just like how it works on person accounts, at least for me on the desktop browser). This would make discussions more clear.
