What steps will reproduce the problem?
1. Loot something that stacks

What is the expected output? What do you see instead?
Expected: No inventory space warning, since number of available slots hasn't changed
Instead: I get a warning whenever I loot simething -.-

Please provide any additional information below.
A possible fix would be using UNIT_INVENTORY_CHANGED instead of ITEM_PUSH as this one _really_ only fires when the number of available slots changes. ITEM_PUSH fires also when an item stacks and is therefore not the best choice here. Otherwise, some more logic checks would be needed.

WOW, I'm only what? 8 months behind... sorry.

Personally, I like the warning even on stacking items because the intent (for me) was to give a warning whenever I add stuff to or attempt to add stuff to my bag and the remaining space threshold is past. This is really useful for multiboxing because full bags should be a stone in my shoe - I WANT to be reminded every time I try and put something in that I have 0 or < n spots left whether the item fit or not.

However, I will see if I could come up with a way to signal you want 'less spammy" notification... assuming the UNIT_INVENTORY_CHANGED actually fires when I want it to.
