I think this is a bug on ZOS side, here is workaround:

local function GetFormatedItemLink(bagId, slotId, linkStyle)
   local link = GetItemLink(bagId, slotId, linkStyle)
   if link == "" then return end
 
   local name = zo_strformat(SI_TOOLTIP_ITEM_NAME, GetItemName(bagId, slotId))
   local data = link:match("|H.-:(.-)|h")
 
   if linkStyle == LINK_STYLE_BRACKETS then
      return ("|H%s:%s|h[%s]|h"):format(LINK_STYLE_BRACKETS, data, name)
   else
      return ("|H%s:%s|h%s|h"):format(LINK_STYLE_DEFAULT, data, name)
   end
end
 
function pickupTest(type, param1, bagId, slotIndex, param4, param5, param6, itemSoundCategory)
   CHAT_SYSTEM:AddMessage(">>>"..GetFormatedItemLink(bagId, slotIndex, LINK_STYLE_BRACKETS))
end
EVENT_MANAGER:RegisterForEvent("MyPickupTester", EVENT_CURSOR_PICKUP, pickupTest)
