you can try this, open up a tab somewhere
write a few things in the editor
then leave that tab
put down your computer for an hour and come back
when you go back to the editor you can still type things and it will "save.." to the API
but when you refresh the page, your text will be gone
and if you write a single character, it will again "save/publish" this to the API
and hence, you will loose what you wrote
