Summary0005270: GUI::LoadComponent crashes (write access violation) when the XAML root is <Grid x:Class="..."> and the component is a UserContro
Description

A UserControl subclass with C++ code-behind calls GUI::LoadComponent(this, "Panel.xaml") from
its constructor. If Panel.xaml's root is a Grid carrying the control's own x:Class, Noesis crashes inside LoadComponent with a write access violation.

Without the x:Class, it is handled correctly:
Panel.xaml(1,1): Root node type 'Grid' does not inherit from LoadComponent type 'Repro.Panel' is
reported through the error handler, LoadComponent returns, and Content stays null. With a
UserControl root, it loads normally.

So the crash needs both the root-type mismatch and the x:Class.
