on drop event not returning correct data type

[Wealthyturtle]

Description

on drop event seems to not be returning an item stack, even though the event value is called event-itemstack

Steps to Reproduce

function f(i: item) :: string:
    return name of {_i}

on drop:
    send f(event-itemstack)

Expected Behavior

event-itemstack should be of data type item stack

Errors / Screenshots

Line 5: The 1st argument given to the function 'f' is not of the required type item stack. Check the correct order of the arguments and put lists into parentheses if appropriate (e.g. 'give(player, (iron ore and gold ore))'). Please note that storing the value in a variable and then using that variable as parameter will suppress this error, but it still won't work. (test.sk, line 5: send f(event-itemstack)')

There might be a workaround for this but it is at the very least misleading.

Just realised this issue would be fixed by #2510
