1) Create a new empty document
2) Switch to the Look tab
3) Collapse all the sections
4) Switch to the File tab
5) Switch to the Look tab
    => all the sections are expanded
    => expansion state has not been preserved

Although harmless, it turns to be pretty disrupting, especially for the demo.
We can live with that in EA.
If there is a safe way to fix that before J1, I buy.
