Steps to reproduce the problem:
1. Type a Javascript below:

window.onkeyup=function(){
	console.log("up");
}

window.onkeydown=function(e){
	console.log(e.code);
}

2. Open a Javascript conosole of Devtools in Chrome Canary 69.0.3473.0

3. ress "Q" key and other keys several times

4. Check the output of the console.

What is the expected behavior?
Keyup event is fired on Q key.
Keyup event should be fired on release of alphabet keys.

For example:

Keys:                 console says:
Press A         ->  KeyA
Release A      ->  up
Press Q         ->  KeyQ
Release Q      ->  up

What went wrong?
Keyup event isn't fired on Q key.
It is fired well on other keys.

For example:

Keys:                  console says:
Press A         ->   KeyA
Release A      ->  up
Press Q         ->  KeyQ
Release Q      ->  NOTHING IS OUTPUTTED

Did this work before? Yes Chrome  67.0.3396.99

* It works on Chrome 67, so this is a regression.
* This bug was already seen in Chrome Canary 69.0.3472.3
* I've reported the same bug in  Issue 856485 , but it has unnecessary information. So I would like to merge  Issue 856485  into this issue.
