Bugzilla

STR:

1. Navigate to  [es6](https://yurydelendik.github.io/old-man-sandbox/sorted-es6/test.es6.html) example
2. Set breakpoint at line 94 of bundle.js
3. Inspect environments/scopes

```js
function comparer(a, b) {
  const ma = /.(\d+)\W*$/.exec(a);
  const mb = /.(\d+)\W*$/.exec(b);
  if (ma == null || mb == null || ma[1] == mb[1]) {
  	return a < b ? -1 : a > b ? 1 : 0;
  } else {
    const na = +ma[1], nb = +mb[1];
    return na < nb ? -1 : na > nb ? 1 : 0; // set breakpoint here
  }
}
```

The function at the specified location contains 3 environments: 

1. function
2. function body
3. if-else.

Chrome has only 2 environments: function, if-else.

Does it make sense to consolidate the function & function body scopes into a single scope? 

Scope content will change during stepping through since new environments may appear/disappear. In other words, it's expected to see scopes less granular on the debugger side, and grouped within function boundary.
