Value of edited variables briefly flash to old value after adding variable to 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 var a = 1; of app.component.ts.

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

6. Set value of variable a to 2.

7. Add variable a to watch panel.

Result: Value of edited variable changes to previous value after adding it to watch panel.

Note: if you step over onto the next line of code, the panel will display the correct value
