WeakRef supported browsers, Once all registered callbacks are performed, the injector will be cleared.customYtElements.whenRegistered. However, since _initializeProperties() and all other related layouting and rendering will be conducted immediately after component registration. Synchorized callback is preferred.polymer_enable_controller_extraction since v1.3.0polymer_enable_sink_wrapper since v1.5.0Chrome 45+ , Edge 12+, Safari 10+, Firefox 29+, Opera 32+
