Following the recent Jira update, there is a UX mismatch when creating child issues within an Epic view. Previously, the input field and the newly created issue were aligned at the bottom of the list.
Now, the inline input field appears at the top of the child issues list, but once created, the new issue is appended to the very bottom. On Epics with many child issues, the newly created task is immediately pushed out of the visible screen area, giving the impression that it failed to create.
