frecon/login: backspace broken in VT after failed login

Reported by anowlcal...@gmail.com, Jan 31 2017

Issue description

UserAgent: Mozilla/5.0 (X11; CrOS armv7l 8872.76.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.105 Safari/537.36
Platform: 8872.76.0 (Official Build) stable-channel nyan_big

Steps to reproduce the problem:
1. Switch to a VT (ctrl-alt-F2/forwards).
2. Enter some text at the "localhost login:" prompt, use backspace, and observe that it removes the character before the cursor.
3. Enter an invalid username/password combo (the username must be at least 1 character long to be able to enter a password).
4. Enter text at the "login:" prompt (NB: now not "localhost login:"), use backspace, and see that it doesn't behave properly -- backspace prints "^H".

What is the expected behavior?
Backspace continues to work at the login prompt after failing a login.

What went wrong?
Backspace prints "^H" after failing to log in.

Did this work before? N/A 

Chrome version: 55.0.2883.105  Channel: stable
OS Version: 8872.76.0
Flash Version: 24.0.0.186

At the initial prompt, arrow keys print e.g. "[D"; after the first prompt, once backspace is broken, they print "^[[D".

Summary: frecon/login: backspace broken in VT after failed login (was: Backspace broken in VT after failed login)
hterm is only the HTML/JS based terminal emulator.  VT's are managed by frecon.

that said, i vaguely recall seeing reports for this in upstream shadow or Gentoo.  can't find them atm.  did come across this though:
