Why does Red Hat Enterprise Linux 7 anaconda not show the pop up to re-enter the kickstart file path if provided with a wrong path?

Issue

• Till Red Hat Enterprise Linux 6, anaconda if provided with a wrong kickstart file path, would pop up a window with an error message saying "can't download kickstart file from this url, please type in a new url were I could find it" and would let the user to enter the new URL once again.
• Now, in Red Hat Enterprise Linux 7, it just says that it can't download kickstart file and it enters into dracut shell, so one can never provide the URL manually if first provided is wrong.
