🔍 AI-Generated Review (multi-model)

[moderate] Public API Surface Design — SetContainerView stores the container without touching HasContainer, so an external backend can end up with ContainerView != null while HasContainer == false (codified by the new test SetContainerViewInstallsAndClearsTheContainerDirectly, which asserts Assert.False(handler.HasContainer) with a live container). In that state the next MapContainerView pass that evaluates NeedsContainer == false short-circuits in the HasContainer setter (if (_hasContainer == value) return;), so RemoveContainer() is never called and the wrapper stays installed and attached for the life of the handler. Either keep the flag in sync when the value transitions between null and non-null, or document/guard that SetContainerView is only legal from inside SetupContainer/RemoveContainer.

}

// Lets a platform-specific handler reject container views that would break the strongly typed
// ContainerView property it shadows (for example the WrapperView-typed property on iOS and Tizen).

This assembly deliberately mimics a platform backend that ships outside of dotnet/maui.
It must NOT be listed in src/Core/src/Properties/AssemblyInfo.cs, otherwise the tests that
consume it would no longer prove that the container view APIs are reachable from a
