### Steps to reproduce

1. Login as a user with permissions to manage documents using Firefox

2. Go to the documents page of a project, and create a document write some content into it

3. Open the same document on another tab

4. Go back to the first tab and log out


### What is the buggy behavior

* The first tab is logged out, but the other tab with the document remains open- and any edits made are still persisted


### What is the expected behavior

1. Once a user signs out via one browser tab, other tabs should not be able to Begin of the insertionmake (persisted) edits toEnd of the insertion Begin of the deletion editEnd of the deletion the Begin of the insertiondocument. NOTE: theEnd of the insertion document Begin of the insertionwould still be visible on the "other tab" and can be edited, but those changes will not be persisted.End of the insertion
