Hah. I've reported a similar issue with attaching an iDevice to a locked Mac in 2014. In my case, iTunes was opening a new space to restore its window in fullscreen mode, and the desktop contents were revealed while the animation was running (the lockscreen reappeared afterwards). Now I'm disappointed that I didn't try to get keyboard input into the system and fully pwn myself :)
