+- [BottomSheet] Fixed crash when bottom bar buttons already have consumer-provided `AutomationId` values.
+
 ## [62.0.0]
 - [StepFlow] **BREAKING**: Removed `StepFlowItem.LockWhenCompleted`. Use `StepFlowItem.CanGoBack` to allow selected completed steps to be reopened before the flow is fully completed, while resetting that step and following steps for confirmation again.
 - [BarcodeScanner] Fixed invalid scan-rectangle validation results restarting detection before the overlay returned to idle by waiting for the reset animation and adding a short cooldown before rescanning.
