Xamarin.Forms loading Xaml with LoadFromXaml is not creating contained objects for a StackLayout - xaml

Question

I'm trying to add to an existing xamarin.forms page, chunks of xaml that will be generated dynamically.
I'm starting my research using the following example from the official docs.
Everything works fine there, but when I try to change the string with the button def for a string with the stacklayout with the button inside, only the stacklayout is inflated, with no children at all.
That's weird, because you can inflate a full page in the example, but it looks like I'm missing something here.
Any advice about how to use LoadFromXaml for partial composite objects?
// MainPage.xaml.cs
void OnLoadButtonClicked(object sender, EventArgs e)
{
string navigationButtonXAML = "<StackLayout><Button Text=\"Navigate\" /></StackLayout>";
var sl = new StackLayout().LoadFromXaml(navigationButtonXAML);
_stackLayout.Children.Add(sl);
}

From the official doc, it's only using LoadFromXaml for single view or a complete contentPage, I also tried LoadFromXaml for layout, and it's loading the layout without its children. For loading layout with children, I'm try debugging with source code, will update later, and as a workaround, you can use layout with contentview like this:
string navigationStackLayoutXAML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ContentView xmlns=\"http://xamarin.com/schemas/2014/forms\" xmlns:x=\"http://schemas.microsoft.com/winfx/2009/xaml\" xmlns:d=\"http://xamarin.com/schemas/2014/forms/design\" xmlns:mc=\"http://schemas.openxmlformats.org/markup-compatibility/2006\" mc:Ignorable=\"d\" x:Class=\"LoadRuntimeXAML.CustomerViewDemo\"> <ContentView.Content> <StackLayout > <Label Text=\"Hello Xamarin.Forms!\" /> <Button Text=\"SECONDB\"/> </StackLayout> </ContentView.Content> </ContentView>";
ContentView contentView = new ContentView().LoadFromXaml(navigationStackLayoutXAML);
_stackLayout.Children.Add(contentView);
Although it's xaml is a little bit more complex, but it can use predefined attributes just as in .xaml, also, elements inside the contentView will be accessible through:
Button secondB = contentView.FindByName<Button>("secondB");
