Fixed Workflow State Dirty Detection and Review Flow (#5283external link)
anchor

MobX observable proxies were being passed directly to structuredClone and JSON.stringify in the workflow state management code, which could cause runtime errors or produce inconsistent snapshots. The WorkflowStateModel.toJS() method was also returning model class instances instead of plain data objects for step properties. These issues have been fixed — workflow state dirty detection, review flows (request review, approve, reject), and list pagination now work reliably.
