Body

When you go to a repository like this one, you are welcomed with the 'old' layout and the repo infos on the right side.

Using the code view beta feature:

Go to any file so the code view layout, then get back to the main page by clicking the repo name in the path of the file which is displayed at the top of the page. The main page shows up, but the code view layout isn't unloaded; the repo infos on the right are missing.

Reloading the main page unloads the code view and the page is displayed like it was before.
