classList not working anymore

[sepans]

The classList attribute stopped working after I updated bower_components. I swapped the polymer and platform directories inside bower_component with the old ones to confirm that it is it.

I have very simple usages like:

this.$.container.classList.add('th-transition-slide'); // container is just a div inside tag

I am getting:
Uncaught TypeError: undefined is not a function Element.js:104
classList Element.js:104
Polymer.init th-reveal.js:14
Polymer.ready th-reveal.js:6
d.makeElementReady base.js:78
...

this is the build.log of the working version:

@sepans Try this:

(this.shadowRoot.container.classList.add('th-transition-slide');)
