Disable (make read-only) the field for course code in the re-run form. This will prevent creation of course runs with a different course code in the course key that are intended to stand for the same course in a program, which presents problems for the course catalog mapping process.
<nav> elements for the actions a user can perform on a perticular
page contain inaccessible label whic causes screen reader users
confusion regarding to their current navigation.
