Steps to reproduce the problem:
1. Navigate to http://www.searsout.com/ (was a typo)
2. Auto-redirected to scam site (in my case http://18.220.180.139/).
3. Audible alert, bogus message, can't close tab or app via tab/window controls, Chrome task manager opens but is blank.  Only way to exit is to taskkill.

What is the expected behavior?
Can close tab at will.

What went wrong?
Site somehow takes over browser, prevents closing tab or app via tab/window controls, have to taskkill.  I have attached a screenshot of browser plus two extras showing history. It appears that mechanism may have to do with reloading page content-- tab was open for less than two minutes while I experimented and took the screenshot but there are hundreds of entries in the history log.

Did this work before? N/A
