When a contract calls a staking precompile, subsequently executes
CREATEorCREATE2, and then reverts while an ancestor catches the failure, the unmatched creation frame causesCaptureExitto pop the wrong synthetic-log boundary. The reverted staking movement remains marked successful and is emitted as a successful Rosetta operation, producing incorrect transaction data and potential reconciliation failures.
