Vue.js + TSX + Storybook 구성이 불가능함

Storybook 패키지로부터 react, react-dom, emotion 패키지의 타입 정의가 컴파일에 포함되는데,
vue에 맞게 intrinsic elements, value-based elements를 타입 호환이 되도록 맞출수가 없다. storybookjs/storybook#7379

템플릿 기반 functional component의 v-for & ref 오동작

부모 컴포넌트에서 functional component엘리먼트에 v-for와 ref를 적용했을때 refInFor가 적용되지 않음.
ref에 지정한 이름의 프로퍼티에 엘리먼트 array로 저장되지 않고 v-for의 마지막 엘리먼트만 저장됨. vuejs/vue#10171 찾아봤는데 vue-template-compiler에 결함이 있다.
