• VSCode Version: 1.1.1
• OS Version: OS X El Capitan 10.11.5

Steps to Reproduce:

1. Create an ES6 class with a constructor

export class AppEnvironment {
    constructor(environment) {
        this.environment = environment;
    }
}

1. right click the environment symbol that's part of the this.environment expression -> click rename symbol
2. Rename the symbol
3. "You cannot rename this element"

I'm aware that this probably doesn't work because it's just not implemented yet. Just want to bring it up to hope it gets implemented.
