I know this might seem like nitpicking, but once you get used to using this link, you want it to be consistent.
The message icon is actually a link in a private message that takes you to the corresponding folder (like the Inbox). It drives me nuts that in certain cases, it’s not a link, specifically with official warnings. It would be awesome if this was consistent across all private message types.
Thanks for bringing this to our attention — this appears to be an oversight in the design of official warnings, but have you noticed this with other types of PMs too?
I’m not sure if there are other PM types than regular messages and warnings. Seems like the missing link is only limited to the warnings. It definitely was working in Discourse 2.x
