Fix for MouseWheelEvent deprecation in TypeScript 3.2
MouseWheelEvent is deprecated and was removed with TypeScript 3.2, however, MouseWheelEvent is still aliased to WheelEvent. For more info see https://github.com/Microsoft/TSJS-lib-generator/pull/579 This PR fixes the build with TypeScript 3.2 by checking the object properties.
