Support browser back navigation

Hi!

I noticed that when I click the back button in browser and navigate back in browser history, it’s often reloading the whole notebook. In fact, navigating between two hashes (for example going to link with #test, then #test2, then back in history) is always triggering reloading of notebook.

I was wondering if there is any way to prevent this reloading and preserve browser navigation?

Thanks a lot!
Daniil.
