[SHOPTIME-3604] Home > Live 진입 후 [back] 버튼 > 다시 Home으로 진입 시 화면 이슈

1. actionTypes.js
2. homeActions.js
3. TabLayout.jsx
4. homeReducer.js
5. HomePanel.jsx
6. RandomUnit.jsx
7. RollingUnit.jsx
8. MainView.jsx

- 원인: 기존의 panel 구조로는 Player를 Full로 시청할 경우 Home관련 elements가 삭제되어 결국 다시 mount 되는 것이 원인
- 대책: panel 구조 변경
