Martin Probst 3ccf5966d7 Adjust polymer attributeChangedCallback to spec. (#40800) ... * Adjust polymer attributeChangedCallback to spec. According to the specification at: https://html.spec.whatwg.org/multipage/custom-elements.html#custom-element-reactions `attributeChangedCallback` is called "given the attribute's local name, old value, new value, and namespace as arguments". This also matches browser implementations and understanding of how things work from discussion with Polymer engineers (CC @rictic). * Fix a dtslint issue with TypeScript <3.0. TypeScript 3.0 and before appears to be confused with the `extends` property declared here.		2019-12-10 10:50:56 -05:00
