XamlParseException thrown when repeatedly opening a control page.

Which version of the app?

WinUI 3 Gallery

Description

1. Run the current build of WinUI 3 Gallery.
2. In the navigation menu click "All" to display the grid of all controls.
3. Click the NavigationView tile to display the NavigationViewPage

Repeat steps 2 and 3 several times (2 to 10 times usually) until a XamlParseException: 'XAML Parsing Failed.' exception is thrown within the generated (NavigationViewPage.g.i.cs) partial class InitializeComponent() method on the last line of this method:

' global::Microsoft.UI.Xaml.Application.LoadComponent(this, resourceLocator, global::Microsoft.UI.Xaml.Controls.Primitives.ComponentResourceLocation.Application);'

(see screenshot below)

This same XamlParseException has also been observed with the ViewboxPage following the same steps.
This same XamlParseException has also been observed with the ViewboxPage following alternate steps clicking the Viewbox tile to open the ViewboxPage alternating with clicking almost anything else in the navigation menu. Again it happens after reopening the Viewbox page between 2 to 10 times.

Start by reproducing the navigation sequence in WinUI 3 Gallery: open All, then NavigationViewPage repeatedly, and compare with the ViewboxPage case. Inspect the generated NavigationViewPage.g.i.cs InitializeComponent() failure and the referenced XAML resource loading. Done means both pages can be reopened repeatedly without the XamlParseException.
