Random bugs:

(This is not a complete list of bugs with polymer.dart. Just the bugs that I ran into. Some of these are feature-compatibility issues with Polymer JavaScript, others are straight-up bugs. Please don't misinterpret, polymer.dart might be useable for you in the meantime. It depends on your app.)
