Description
In a .NET 8 Windows environment, there is an issue where placing a BoxView inside a Border results in incorrect sizing. When BoxView and Border are placed separately, there are no significant issues. However, when a BoxView is nested within a Border, both the Border and BoxView are rendered at incorrect sizes.
This problem has not been observed in Android and iOS environments. It appears to be an issue exclusive to the Windows .NET 8 platform.
