Bug: Test Misconfiguration Affects Event Verification
The "does not publish events for other transaction statuses" test spies on the rootMessenger instead of the controller's own messenger. This prevents it from accurately verifying the MultichainTransactionsController's event publishing behavior, making its assertions ineffective and inconsistent with other event-related tests.
