Issue : Not maintaining the Edit/Preview state

Issue : Not maintaining the Edit/Preview state

- Open a doc. and click "Preview" and leave it in the same state.
- I've opened many documents in multiple tabs and changed to "Preview" state.
- Then, I tried to navigate the doc. opened in the different tabs, it gets loaded again and the state is changed to "Edit mode"

I like to have the docs. in the same state "Preview" state (and load the same document again only when needed)
