How to save and restore editor state in memory

[MartinJaskulla]

I would like to save the current state of the editor in memory, then mount a different editor and restore the state including working undo/redo functionality.

These threads make me believe this is possible, but I cannot make it work:
https://discuss.prosemirror.net/t/how-to-restore-history-data-when-using-single-instance-of-editorview/5819
https://discuss.prosemirror.net/t/possible-to-store-history/823

I created a minimal reproduction:

• git clone https://github.com/MartinJaskulla/tiptap-restore-edit-history.git
• npm start
• Make some edits in the editor
• Click "Persist"
• Click "New editor" (destroys editor and mounts new one)
• Click "Restore"

After the restore the previous content is displayed, but undo/redo does not work and after typing a few characters I get an "Uncaught RangeError".

I am saving editor?.state and then trying to restore it via editor?.view.updateState().

@MartinJaskulla I encountered the same problem. Did you manage to assign a saved state in any way?

It is worth noting that on the vanilla prosemirror everything works properly and no errors occur
