Material settings: opening animation of large lists is not smooth

Reported by woxxom@gmail.com, Jun 13 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3129.0 Safari/537.36

Steps to reproduce the problem:
1. install the attached extension
2. click the extension's icon and click "Generate random cookies"
3. click "Cookies" in the browser settings

What is the expected behavior?
The "cookies" sub-page appears with smooth animation immediately after click

What went wrong?
After a delay the sub-page appears but there's a visible jerkiness: the animation is not smooth. It doesn't even look like animation, but rather a slideshow.

Did this work before? N/A 

Chrome version: 61.0.3129.0  Channel: canary
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

* The extension is provided only to generate 2000 domains with cookies. If use the browser a lot you'll have even more cookies in a matter of months. The extension has a button to remove all generated cookies.

* This might be not a bisectable regression, but rather an inherent problem with how large lists such as Cookies are populated in Material Settings.

* As for a solution, it might be possible to animate after a 100 or so domains are processed. Or maybe there's a simple method to use lazy-rendering for off-screen content in Polymer.

@dschuyler: I believe, this has already been fixed by moving the cookies list to a different page and using iron-list. Can you confirm?

I can confirm that this should be much faster* for m-63.

woxxom@ kudos on the cookie generator extension.


*or fixed for a few thousand cookies cookies. It's much faster in m-63, but at some N number of cookies it will still take time.
