| Notes on Polyfill compatibility in tests: |
| - Test elements loaded via imports, to ensure load order correctness |
| w.r.t. Polymer.mixin being availbale |
| - Resize notifications and asserts are done asynchronously, since |
| there are timing differences w.r.t. when detached callbacks occur |
