Issue with NavigationPage.SetHasNavigationBar

When I navigate to a page with NavigationPage.SetHasNavigationBar(this, false); and go back there is a gap on the bottom with the size of the navigation bar. This bug only appears only on iOS. Android works normal.

public partial class SearchPage : ContentPage {
    public SearchPage()
    {
        NavigationPage.SetHasNavigationBar(this, false);
        InitializeComponent();
    }
}
