Why is Google hiding the cached snapshot of Google+ Pages

If you do a cached snapshot of a Google+ Page you get a blank screen,

http://webcache.googleusercontent.com/search?q=cache:https://plus.google.com/104044418361598053077

Delve a bit further and look at the sources and you see,

“body { visibility: hidden;}”

Strip the cache by using &strip=1 to see text only view and you get the cache,

http://webcache.googleusercontent.com/search?q=cache:https://plus.google.com/104044418361598053077&strip=1

Anyone know why Google are trying to hide the cached snapshot of Google+ Pages?
