Values of closure variables read 'not available' in watch panel

[Shenniey]

This issue only occurs on Microsoft Edge (Chromium) and not on EdgeHTML.

Step of reproduce: (Repro Gifs has been attached)

1. Run below commands in a command prompt:
   npm install -g @angular/cli
ng new my-app
cd my-app
ng serve

2. Open my-app folder in another command prompt.

3. Configure the Edge debugger with launch.json file.

4. Set breakpoint at title = 'my-angular-app2; of app.component.ts.

5. Launch Microsoft Edge (Chromium) against localhost(F5).

6. Add a Closure variable to the watch panel.

Result: Value shows up as 'not available' in watch panel (it is still correct in variables panel)
