Regression: .net nuget packaged controls not presentable when referencing from C++ project

Describe the bug

This is a regression beginning from version 1.4.5: 1.4.240211001 upwards. Version 1.4.4 backwards doesn't have such issue.

When I create a C# Class Library project, referencing some components provided by other nuget packages (like CommunityToolkit.winui.ui.controls), then reference the C# library from C++ project according to Walkthrough—Create a C# component with WinUI 3 controls, and consume it from a C++/WinRT app that uses the Windows App SDK, the components from the nuget package.

Steps to reproduce the bug

Sample xaml in C# class library project (with nuget reference: CommunityToolkit.WinUI.UI.Controls):

<?xml version="1.0" encoding="utf-8"?>
<UserControl
    x:Class="Grid2.GridWrapper"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Grid2"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:controls="using:CommunityToolkit.WinUI.UI.Controls"
    mc:Ignorable="d">

    <StackPanel Width="500" Height="500">
        <controls:RadialGauge x:Name="RadialGauge"
                              Width="280"
                              IsEnabled="True"
                              IsInteractive="True"
                              MaxAngle="150"
                              Maximum="240"
                              MinAngle="-150"
                              Minimum="0"
                              NeedleLength="60"
                              NeedleWidth="4"
                              ScalePadding="0"
                              ScaleTickWidth="0"
                              ScaleWidth="12"
                              StepSize="30"
                              TickLength="6"
                              TickSpacing="15"
                              TickWidth="2"
                              ValueStringFormat="N0"
                              Value="120" />
    </StackPanel>
</UserControl>

Then Create a C++ project to reference such user control

Expected behavior

The control provided by the nuget package should present with no issue.
