ClientScript error while hovering over sort buttons on spellbook interface

[vddCore]

Detailed description
Whenever you have any offensive spell with defensive XP enabled set while wielding an elemental staff, the spellbook interface fails to properly process mouse hover and left-click events on the sorting buttons. Right-click opens a menu but the Sort option does not work. The non-defensive setting works properly.

Steps to reproduce

1. Wield any elemental staff.
2. While having proper runes to cast an offensive spell, go to combat styles and set an offensive spell with defensive XP as auto-attack.
3. Go to spellbook interface.
4. Hover over the sorting buttons.

Did a small deep dive into this. It appears to be a server sided issue. Seems like certain varbits are not being set leading to a client script error. However, I have had trouble in the past with almost all of the "tabbed" interfaces on 530 when decompiling them. Just some extraneous values.
