Using `yield` hangs IDE

[dungwinux]

Version

{
  elementaryJS: "c122f37",
  ocelot: "6887ff2"
}

Problem

When explicitly using yield in a generator function, ElementaryJS detects this as SyntaxError (SyntaxError: Unexpected strict mode reserved word). However, Ocelot hangs due to the error being uncaught.

Interestingly, using yield in an anonymous generator function works fine, and ElementaryJS doesn't detect as error.

Step to reproduce

1. Input the below javascript code:

function* generator() {
    yield 1;
    yield 2;
}
const range = generator();

Expected behavior

Print error in Ocelot console

Actual behavior

Ocelot IDE hangs. In developer console, it prints out error as below:

Closing, same as the other error.
