Memory Leak in WatchOS 11.2 with NavigationTitle in Presented Sheet

I would like to report a memory leak issue in watchOS 11.2 that occurs when using .navigationTitle() inside a sheet. This behavior is reproducible both on the simulator and on a real device, but not on iOS. While this does not register as a leak in Instruments, the deinit of the DetailsViewModel is never called, and multiple instances of the view model accumulate in the Memory Graph Debugger. Commenting out .navigationTitle("Sheet View") resolves the issue, and deinit prints as expected. Using @MainActor on the DetailsViewModel does not fix the issue. Nor does switching to @StateObject and using ObservableObject resolve the memory retention.

This issue seems related to other SwiftUI memory leaks that have been reported:
