Well, sometimes it is a clean presentation to not be able to select text. You know when you just randomly click and hold the mouse then you end up highlighting half of the interface as well as the text? That is "immersion breaking" for web apps, or whatever the real word is.
In this specific case, it's still broken because the cursor still changes to the selection cursor. Oh well.
I guess the joke is that there is a Justin Bieber song called "Sorry". At least I think what's going on here. "404s and Heartbreak" with a pic of Kanye West would have been something else along this line.
Yeah I don't get it. I guess the only other thing that stood out for me was that the message is "Sorry something went wrong" except that 404 is a user error. "Sorry" is usually used for 500s.
