SeleniumHQ/selenium#9264

logMutationEvents does not work for me in the JavaScript bindings. The defined callback is never executed. When looking into the browser console of the controlled Chrome instance, the following error is logged:

Uncaught ReferenceError: __webdriver_attribute is not defined

This does not seem to be caught by the tests, because the test's assertions are located in the callback that is never executed.

To Reproduce

Detailed steps to reproduce the behavior: Execute the self-contained script mentioned below. Apart from executing logMutationEvents, it also prints the browser console logs.

Expected behavior

As the DOM of the page is being mutated during the script, the callback passed to logMutationEvents should be executed.

Test script or set of commands reproducing this issue

This repo just adapts the test code for logMutationEvents.

Run it with:

1. npm install
2. npm start
