Polymer 2.0 preview Issue - Computed Bindings stopped working with this commit

[marybeshaw]

Description

I updated my polymer 2.0 preview installation, and computed bindings as well as individual observers stopped working.

Computed binding (such as _getContainerClasses below) is not called:

<div class$="[[_getContainerClasses(centered)]]"></div>

Individual Observer function such as (observerFunction below) is not called:

      static get config() {
        return {
          properties: {
            property: {
              type: "String",
              value: "[]",
              observer: "observerFunction"
            }
          }
        }
      }

Live Demo

Spinner element (which uses a computed binding; I simplified it for sharing):

Steps to Reproduce

When I pin to commit Polymer/polymer#5c1b11ff0f0b96665f40179e53f2d21a955ef605, unit tests in the second jsbin work.
When I pin to commit Polymer/polymer#38fa1f6b09d03f53115b741a8ce0c27b8bd84f30, the same unit tests do not work.

Expected Results

When I update my installation of #2.0-preview, computed bindings (and individual observers) should work.

Actual Results

When I update my installation of #2.0-preview, computed bindings (and individual observers) DO NOT work.
