Steps to reproduce the problem:
Simple server that asks basic auth with default browser window (in desktop browser it looks like on screenshot1). After auth simple html page with one text input will be rendered.

1. Open new tab in incognito mode
2. Be sure that auth window appeares
3. Enter correct login and password
4. When target page is rendered tap on input (focus) and try to enter some cymbols.

What is the expected behavior?
Text cursor appeares and every keypress change input value 

What went wrong?
Cursor doesn't appears
Input value doesn't change after key press

If you make events subscription with addEventListenet to input you will notice that 'keyup' and 'keydown' events work correct, but browser doesn't fire 'input' event.

Did this work before? N/A 

Chrome version: 60.0.3112.107  Channel: n/a
OS Version: 6.0.1
Flash Version: 

Very strange that:
1. ASUS Zenpad Z380KL allows to type numbers in landscape
2. Lenovo A5000 doesn't allow to type anything in portrait but if you rotate smartphone to landscape you will be able to enter numbers

Actualy, this problem can be reproduced without incognito mode. You just need to clear cache totally and do all the steps. You can reload page and the problem will gone.

I faced this problem when user tried to use my project first time and couldn't enter value. He reloaded the page and this solved the problem.

After some research i decided to reproduced it in incognito and i think this is the same problem
