[runtime] script evaluation should return the value of last Statement that returns value

[croraf]

Describe the bug https://tc39.es/ecma262/#sec-block-runtime-semantics-evaluation with focus on NOTE 2

To Reproduce

1;
const a = function () {};

Expected behavior Should return 1. Instead undefined is returned.

This isn't really a bug, it should output nothing. If you run this in Node you won't get 1 as an output either.

Thanks for that, I don’t get that locally for some reason. Is this something you wanted to look at @croraf ?

Maybe related to #1544

This has been fixed for a while. The example now returs the expected 1.
