ESOUI - [open] EVENT_INVENTORY_SINGLE_SLOT_UPDATE issue with Filleting Fish at Station

This may not exactly be a "BUG" but I find the behavior here odd and possibly unintentional.

- In this example I'm filleting a stack of 5 salmon at the provisioning station. The only addons I'm using here are pChat to expand the chat window a bit (same behavior w/o enabled - just using this for the screenshots below) & a little addon I made that registers an event handler for EVENT_INVENTORY_SINGLE_SLOT_UPDATE and prints out some debug:

Code:

-- EVENT_INVENTORY_SINGLE_SLOT_UPDATE

local function InventoryUpdate(eventCode, bagId, slotId, isNewItem, itemSoundCategory, inventoryUpdateReason, stackCountChange)

    local newItem = isNewItem and "TRUE" or "FALSE" -- turn boolean into a string



    -- Get the stack count & itemLink for this bag slot

    local _, stack = GetItemInfo(bagId, slotId)

    local itemLink = GetItemLink(bagId, slotId)



    -- Print Debug

    d("Inventory Update: Slot ID: " .. slotId .. " " .. itemLink .. ": Current Stack = " .. stack .. ", Change Count = " .. stackCountChange .. ", Is New Item = " .. newItem)

end

There is an EVENT_INVENTORY_SINGLE_SLOT_UPDATE for every single Salmon that gets removed, and every single Fish that gets added.
Note that for every one of these events the values returned by GetItemInfo(bagId, slotId) return the same stack count of either 0 (for the Salmon) or 5 (for the Fish). This is the value for that slotId after all of these events has resolved.

Now for comparison, if I use the 5 fish I filleted in order to craft some Fishy Sticks:

There is only a single EVENT_INVENTORY_SLOT_UPDATE for each item. The stack of 5 fish is decremented to 0, and the stack of 16 Fishy Sticks I had in my inventory incremented to 36. The values returned by GetItemInfo(bagId, slotId) return correctly here.
At some # of fish filleted instead of the multitude of events you get same behavior as standard crafting. I'm not sure how many fish, 25 still throws a million events, I think somewhere around 50 fish you'll finally just get one stack update for each type.

This doesn't really stop anything from working. But it seems a bit odd since normal crafting doesn't work this way - this is also quite a lot of UI events to be going off at once. This behavior throws off my inventory indexing function in LUIE that displays items consumed/crafted when crafting, since as soon as the first event fires that shows 1 fish has been removed, checking the slot returns an empty slot. (I can write a workaround for this - but I figured I'd post this up here first).
