Description

Paper-Input: Auto-Validation fires directly for required without any user interaction Since nothing has been entered so far, the validation fails of course.

Live Demo

A working example based on "polymer init" can be found here: https://github.com/rowe42/PaperInputValidationError

Steps to Reproduce

1. Clone Repo
2. bower install
3. polymer serve
4. run in Browser ==> Page only contains one input field, which turns red through validation instantly.

Expected Results

No validation until the user has entered something.

Actual Results

see above
