Steps to reproduce the problem:
1. Open DevTools => Console
2. Paste this code:

var a = function () {
    !function b() {
        b.id || (b.id = 666);
        debugger
        console.log(b);
        alert(b.id)
    }()
};
a();

3. Stop on "debugger".
4. Hover variable "b" or write it to "Console"

What is the expected behavior?
it have to show "b" function

What went wrong?
Uncaught ReferenceError: b is not defined

Did this work before? N/A 

Chrome version: 68.0.3440.106  Channel: stable
OS Version: Mint 18.3
Flash Version: 

alert(b) and alert(b.id) works fine, but DevConsole say`s "is not defined"
