js-interop: NoSuchMethodError when compiled to JavaScript

[rillomas]

Describe the issue you're seeing
I get the following error when I access a web page built by pub build

NoSuchMethodError: method not found: 'open$0' (J.getInterceptor$x(...).open$0 is not a function)

Does it happen in Dartium or when compiled to JavaScript?
This is happening after the code is compiled to JavaScript.
I checked in Dartium and Chrome and both had the same error.

• Dart SDK version: Dart VM version: 1.15.0 (Wed Mar 09 10:07:59 2016) on "windows_x64"
• pkg/js version: 0.6.0

Failing code:
https://github.com/rillomas/js_interop_issue

1. pub get
2. pub build
3. cd build/web
4. python -m SimpleHTTPServer
5. access localhost:8000 with a browser and open the console to see error

if you comment out the following line in index.dart, the code will work properly.

_heartbeater = new Timer.periodic(HEARTBEAT_INTERVAL, _pulseHeartbeat);

Please disable 'minify' and show stack trace.

- $dart2js:
    checked: false
    minify: false
    sourceMaps: true

maybe duplicate: #25785

I got the following stacktrace after disabling minify

Yes it is the same issue.
