- Remove debounceAnimationFrame from board_sidebar_epic_select.vue
(Move mutations inside setActiveIssueEpic action)
- Add cache for fetched epic data in vuex store.
- Add logic for fetching epic if it doesn't exist in cache.
- Remove settingEpic state from BoardSidebarEpicSelect
(It's redundant and we should use epicFetchInProgress from vuex)
- Change the event name onEpicSelect to epic select.
