Al: JsonArray.IndexOf returns -1 when searching for added values

[bjarkihall]

Describe the bug
JsonArray.IndexOf doesn't seem to find the index of values (specifically Integers previously added). The debugger shows that the array is populated like (e.g. [1] or [1, 2]) but searching for their indexes always returns -1.

To Reproduce

1. Run the following procedure:

local procedure foo()
var
    arr: JsonArray;
begin
    arr.Add(5);
    Message(Format(arr.IndexOf(5)));
end;

This is just a simple sample but I've been trying to find indexes of Texts (you could just do Format(1)), JsonToken (only works after using JsonArray.Get, but that assumes you know the index either way), JsonVar and so on.

Expected behavior
Message prompts with the correct index 0.

Same issue here. Do you guys know of any workaround? Looping I guess? :-)
