[UX] Jump list doesn't scroll

[Revenent 15]

Noticed this after the 4.6 update, but when I'm browsing music by songs, the jump list (links to the letters on the right) doesn't scroll, and because I have foreign songs, the list is higher than the screen.

I can't see any letters before L, and any after "真".  According to the DOM, there are 14 more entries.

Not sure if you need the server logs, since this doesn't seem to be a server issue, but a UX issue.

Hi, yes I think we're probably just going to cap the number of entries that we put in there.
