Describe the bug
Sometimes when i try to use a [mod:alt] macro its disenchant a random item on my backpack

How to reproduce
As mage 90 im using a Food macro like this:

#showtooltip
/use [mod:alt] Conjured Mana Pudding; Conjured Mana Buns

The macros was binding in the 10th position of the Action Bar 4, using the default wow UI

sometimes disenchant a random item on my backpack, last time was the "Nat Pagle's Extreme Angler FC-5000" item, the item is in the 10th position in my backpack, i had to recover the item using the restoration blizzard page

What did you expect?
Dont intervene with ALT macros, or validate addon addon to only work while the Backpack is open or the trade window is open, and dont while clicking an ActionBar

Screenshots
I dont have a screenshoot at this moment
