I am testing Leap build 115.1 on Virtualbox Version 5.2.6 r120293 and my OS
version is mac OS High Sierra Version 10.13.3. During the installation when I
am asked to select User Interface, if I select 'Custom' and click next, then
click back to the User Interface selection, then click next again, an error
would occur saying "SetOverlay called when old overlay was not cleared"

Reproducible: Always

Steps to Reproduce:
1.Boot using build 115.1 iso
2.proceed to User Interface, click 'Custom' then 'next'
3.Make no change to the software selection, click 'back'
4.Now you are back to the User Interface, and the selection should still be
'Custom'. Click 'next' again and an error will pop up.
