Reproduction link

Steps to reproduce

• Run the app
• Look at the console

What is expected?

The error is thrown once

What is actually happening?

It is thrown twice

This is expected: it's possible that your code in the globalHandler itself has errors, and that error is thus reported as a potential error in your error handling code.

If you already have an error handler, you should not be throwing the error.

Yes, errors in the global handler should be thrown, but only once and not twice. Or am I missing something?

If you already have an error handler, you should not be throwing the error.

If I don't throw the error then the error get's completely swallowed: https://jsfiddle.net/d6uqhk0r/

(Thanks for Vue, it's super impressive how much you achieved.)

This is now fixed - note that to avoid the error being logged twice, you need to throw the original error instead of throw new Error(err).

Awesome thanks
