Image "Raycast Target" doesn't block clicks, since when?

Unity Engine
1

Hi,
So I have this issue in which an Image with Raycast Target option on will not blocks clicks, i.e. a button behind image will still get clicked. I can fix it with adding a blank button or Interactable component, But I could bet money on the fact that It used to block clicks on the past. Am I wrong ? Using unity 2017.1

EDIT:// ok just found that in 5.6.2 this option will block the clicks, wondering why they change it… It’s kind of annoying.

This may be a bug?
