Small Rune page bug

When in champ select, if you currently have rune page 3/5 selected (assuming you have 5 pages), and you go to edit that page by clicking the edit rune page button, it auto selects the first page in the rune list 1/5. It's supposed to stay on the page you previously had (3/5) so you can edit it (3/5). But since the current patch it goes from 3/5 to editing 1/5.

Yeah, it's small. But it really threw me off one game and it's actually rather annoying.

Would appreciate reverting it back to previous functionality.

Thank you! -Ace
