Icons get stacked on the cursor when picking up multiple items simultaneously.

It can be reproduce with a simple script.

--global script
for _, ob in pairs(player.cell:getAll()) do
    if ob.type == types.Miscellaneous then
        ob:activateBy(player)
    end
end

If this script is run while inventory is open, icons of items gets stacked on the cursor and cannot be fixed until game restart.
