Just found the effect showed in the image above.
1- make one course backup, you'll end in the file browser.
2- click the "course" link in the browser breadcrumb.
3- you'll see all the possible areas in a tree, with the "course" area again.
4- click in the "course", the tree expands and back to 3 (hence recursion).
I don't know how that is expected to work but current behavior looks incorrect.
