Steps to reproduce the problem:
1. Configure a proxy with user/password in Chrome
2. Open any web page. It will ask for user and  password. Type it.
3. Open application. It will not connect, and will display error: Connection error: Proxy Authentication Required

What is the expected behavior?
In previous Chrome versions, after step 2, app connected successfully

What went wrong?
1. Proxy auth is not keeping data between browser and packaged app.
2. If this is a new behaviour, proxy auth should trigger an auth dialog when required.
