* Note: we do not use the persist state plugin because
* it is not impossible for a user to have two windows at
* the same time. The persist state plugin is just overriding
* everything with the current state. This isn't good because
* if a draft is created in one window and another draft is
* created in another, the draft in the first window will just
* be overriden.
* Here, we can't guarantee 100% atomicity unless one uses
* different keys, which will just pollute the whole storage.
* It is indeed best to have backend support for this.
