Profile picture navigation through arrow keys not working

[Nisto]

I'm not sure if I'm just doing it wrong, or if it's actually a bug, but I'm going to guess it's the latter. Anyway, navigating through uploaded artist profile images through the keyboard arrows doesn't seem to work. I've tried different browsers, too, not working - the preview frame just closes down. And of course, I'm sure there are actually more than one picture on the profiles I'm trying it on.
