label to "if" statement is not recognized and crashes on break

[yoctoserge]

Such code (result of transpiling):

console.log("Hello from NJS JavaScript");

foo: if (bar()) {
    console.log("This prints:");    
    break foo;
    console.log("This will never print.");    
}

console.log("Because execution jumps to here!");

Thrown:
SyntaxError: Illegal break statement in /app/hello-world.js:5
