Do you mean that the system sometimes fails to create a snapshot of the note before the latest edit?

If so, are the following statements valid?
Expected vs. Actual Behavior

Expected: Any edit on a note should trigger Joplin to create a historical record if "Historical Version Recording" is enabled, allowing the user to revert to the last version even if the note initially has no history.
Actual: For notes without any historical versions, editing does not always save the state prior to the edit, leading to a lack of revertible versions.
