Hmm... I'm not sure if it's the same thing, but I've noticed that if you press the left or right arrows of your keyboard (esp. if you want to fix a typo), it'll direct you to the previous fanart like Stella said. When that happens, you can just backspace to the previous page you were on, and your comments should still be there. That is, if you don't want to keep C&Ping everything over and over again.
It's happened a couple of times to me, so now I just click the space that needs to be corrected. It's a little annoying when I forget sometimes though lol.
