Steps to reproduce the problem:
1. Open the devtools
2. Type the following code:
class toto {
   bindEvent() {
     document.addEventListener('keyup', (event) => {
       debugger;
       console.log(this);
     });
   }
}
new toto().bindEvent();

3. select the html window and press a key

What is the expected behavior?
In the Scope debugger panel, when the breakpoint is reached, "this" should be "toto {}".

What went wrong?
"this" appears to be the document element.document.

But typing "this" in the Chrome console correctly returns "toto {}".

Did this work before? N/A
