Taint problem with SpellBookFrame

Hi, I'm trying to write a small addon to enable the mouse wheel on the pet spellbook. The code works fine to navigate the pages, but I have a problem with taint. As soon as I use the mouse wheel on the pet spellbook, any action on the spell buttons in the pet or the normal spellbook is blocked, apart from dragging them to the action bar.
Lua Code:
  1. SpellBookFrame:HookScript("OnMouseWheel", function(self, value)
  2.     if self.bookType ~= BOOKTYPE_PET then return end
  4.     local currentPage, maxPages = SpellBook_GetCurrentPage()
  6.     if value > 0 then
  7.       if currentPage > 1 then
  8.         SpellBookPrevPageButton_OnClick()
  9.       end
  10.     elseif currentPage < maxPages then
  11.       SpellBookNextPageButton_OnClick()
  12.     end
  13.   end)

Here is the taint log I get when I right-click on a button to toggle autocast (no other addon loaded):
