@Obsidian - at a minimum it would be useful to know if this can be done externally through a plugin that would be able to save and restore the editor state.
attempting to answer my own question.
Found this dead plugin
It doesn’t seem to work but at least seems that it may be possible to fix through a plugin. Although this should be a native feature and I suspect Chrome already supports it out of the box since the browser tab position is saved across restarts.
