Steps to reproduce the problem:
1. Use authenticated proxy
2. Try to acess some pages not whitelisted on proxy
3. Put username and password
4. Stuck in blank pages

What is the expected behavior?
Page load

What went wrong?
Stuck in blank page.

Did this work before? Yes 

Chrome version: 66.0.3359.139  Channel: stable
OS Version: 10.0
Flash Version: 

The company proxy ask for password to access web pages not whitelisted, and a popup shows to ask username and password when the page is not whitelisted.

Before this update the autentication worked well and redirect to the web page accessed. But after that update, the Chrome do not redirect and stuck in a Blank webpage, but after that, if I try again to access the web page it works because the credentials is already saved.

I tested it on Windows 7, Windows 10, Windows Server 2012 R2 and the result are the same. The problem is not the proxy because another web browser works well.

Thanks for helping.
