Closing settings pane does not de-allocate the memory used

[ejbills]

I have an app that uses this package, in which the views are rendered with SwiftUI. Upon closing the settings window, the memory that is allocated to the panel does not get released, leading to a permanent memory allocation during the lifetime of the app. In a particularly heavy SwiftUI view, this can easily surpass 100mb. Has anyone else had this issue? Thanks.
