Cannot detect Angular from remote device

When debugging on android via usb and chrome's dev tools, the plugin cannot find detect angular.

Steps to reproduce

- server angular app (`ng serve`)
- connect android device via usb
- load angular app via IP address
- navigate to `chrome://inspect` and inspect the device
- open angular section of the devtools

Devtools will try to find angular but will fail.
Not sure where the disconnect is.

Reproduce the failure by serving an Angular app with `ng serve`, loading it on an Android device over USB by IP address, and inspecting it through `chrome://inspect`. Start by tracing why the Angular section of the devtools cannot detect the remote app. Done means Angular is detected in this remote-device workflow; no source files or tests are named.
