This is from a New York Times article :
The ghost of Diana gone rogue animates the fractured fairy tale of Meghan and Harry, and their intemperate attempt to upend centuries of starchy rules and break away from the Firm.
I looked up the adjective 'rogue' in the Merriam-Webster dictionary :
1 : resembling or suggesting a rogue elephant especially in being isolated, aberrant, dangerous, or uncontrollable
3 : of or being a nation whose leaders defy international law or norms of international behavior rogue states
I am curious which of the following "gone rogue" means in this context.
seen as rebelling against the established norms and expectations of the royal family
passed away in a state of isolation from the royal family
