Expected result.
N/A.
Steps to reproduce.
1. In Main Menu select Options to open Game Menu.
2. In Game Menu select Game Options. This should bring Game Options window with UI tab selected.
3. Move the cursor over a tab that is not currently selected (for example Online) and rotate the mouse wheel.
4. Repeat step 3 for wheel, right, left mouse buttons.
Game version.

Comment.
Is this behaviour intended?
There are other windows affected by this issue.
Character Sheet: General, Attack, Defense, Talents, Equipment. But not Levelup or Manage Inventory (only LMB)
Inventory: Main set, Off set. Item filters can only be selected with LMB or RMB.
It seems like Game Log in Message Log has this issue as well.
