Not all errors (in module) are captured by the listener

Some syntax errors are not captured by the event listener when originated in a module.

Syntax errors inside a module in situations like:
        function a() {  // missing closing bracket

won’t get captured by the listener.
While other errors like:
        const a = 1
        a = 2

will get captured, even when generated inside the module.
This works as expected in FF and Chrome.

In the attachment a demo with 4 examples.
