Hm, another (untested) solution how to change zoom animation:

local function CreateSlotAnimation(inventorySlot)
    if inventorySlot.slotControlType == "listSlot" then
        local control = inventorySlot
        local controlType = inventorySlot:GetType()
 
        if (controlType == CT_CONTROL and control.slotControlType == "listSlot") then
            control = inventorySlot:GetNamedChild("MultiIcon") or inventorySlot:GetNamedChild("Button")
        end
 
        if (control and not control.animation) then
            control.animation = ANIMATION_MANAGER:CreateTimelineFromVirtual("IconSlotMouseOverAnimation", control)
            control.animation:GetFirstAnimation():SetEndScale(1)
        end
    end
end
ZO_PreHook("ZO_InventorySlot_OnMouseEnter", CreateSlotAnimation)
