Steps to reproduce the problem:
1. Create a blank page.
2. Add some mechanism to debug js erors either ith window.onerror or the error event
3. fire a change event in any DOM element using javascript (body is a good candiate)
4. Observe the errors.

I did a codepen with the described: https://s.codepen.io/academo/debug/oPVEzm/DqrDdKGpeGgr

What is the expected behavior?
The event should fire event listeners in the element without errors.

What went wrong?
A "Script Error." is generated without any other information about the error and the event listeners are fired normally. 

Did this work before? N/A 

Chrome version: 69.0.3497.71  Channel: stable
OS Version: 11.4.1
Flash Version: 

Without devtools in Chrome for iOS I can't gather more information about this error, other than generating that script error without any more information everything works as expected.

This error started and kept growing at the same time Chrome 69 for iOS was released, currently is generating us thousands of errors per minute as one of our scripts fires a change event in a input field when the page load.
