Menu
Hi I'm just playing around a bit with polymer and got a problem.
First here is the Page I'm editing: http://beta.sgbvm.de/app/site/berichte.php
The most things works pretty well (e.g. transitions etc) but when i scroll down the list and then click on a card the site stays at the bottom, but i want it to scroll up.
By now i searched the for nearly 5 hours but i cant figure out how to scroll back to the top after i click on a card.
I read something about accessing the shadowDom but i didnt unterstand what they where talking.

core-header-panel provides a scroller property which gives you access to the internal scrolling div. From there, you can use vanilla JS to scroll it (using scrollTop).
document.querySelector('#mainContainer').scroller.scrollTop = 0;
