On Ghost Control Panel, when configuring Navigation Items Link, I can't change link to Github domain, they keep change back to localhost. I Know this is happen on Ghost side, but are there any workaround to solve this? <img width="1096" alt="screen shot 2018-06-07 at 21 54 34" src="https://user-images.githubusercontent.com/11798147/41104203-6a5605ca-6a9d-11e8-9828-4980275c8f8f.png">
