/**
|
|
* Per-tab memory of which thread the docked assistant panel had open.
|
|
*
|
|
* The panel's state lives in React only, so a full page reload (the "Ladda om"
|
|
* deploy prompt, a browser refresh, a crash recovery) closed it and dropped the
|
|
* thread from view; the user had to dig it out of "Tidigare konversationer" by
|
|
* hand. This remembers just enough to reopen the same thread after a reload:
|
|
* the conversation id (the thread itself is already persisted server-side),
|
|
* the intent that shaped it, and whether the panel was collapsed.
|
|
*
|
|
* sessionStorage on purpose, not user_preferences: this is "this tab, this
|
|
* session" state. It survives a reload of the tab and nothing else, so a
|
|
* thread never follows the user to another device or another tab, and a closed
|
|
* tab forgets it. Nothing here is authoritative: the id is re-validated by the
|
|
* conversations API on restore, and a thread that no longer opens is dropped.
