Steps to reproduce the problem:
1. In Angular2 web app, use observables to call an api
2. create local, class level variable
3. assign response from api call to the local variable
4. in debug mode, check the value of response and local 
    variable

What is the expected behavior?
That the debug tool in chrome dev tools will display the value of the local variable properly

What went wrong?
The local variable, when moused over, would display as undefined, but would actually have the value from response saved properly.  This is not an issue of moving the value from response to the local variable, but the local variable not displaying its value properly.  See attached to get a better understanding.

Did this work before? N/A 

Chrome version: 58.0.3029.110  Channel: n/a
OS Version: 10.0
Flash Version: Shockwave Flash 25.0 r0

As you can see in the pictures, the local variable allDocuments does get populated correctly, but dev tools isn't showing the value of the variable when moused over.
