A players previous block break location is held onto permanently, and if an interact event is cancelled, the client sends a stop breaking block packet This then tries to update client about that old location. This old location might then be in a now unloaded chunk, and it caused it to load. We now also clear reference to it once abort destroy block is ran to stop trying to send updates about the old block anyways.
