InvalidCastException in Dialog.get_DialogWidth()

Describe the bug

When retrieving the DialogWidth or DialogHeight properties in an existing Dialog control, an InvalidCastException is thrown.

To Reproduce

1. Create a Dialog control in XAML with assigned DialogWidth/DialogHeight properties.

<!-- ... -->
    xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml"
<!-- ... -->
<ui:Dialog x:Name="SomeDialog" Title="Cool Title" ButtonLeftAppearance="Danger" ButtonLeftName="Bad Button" ButtonRightAppearance="Secondary" ButtonRightName="Meh Button" DialogHeight="300" DialogWidth="250"/>

2. Attempt to retrieve the fields programmatically.

using System.Diagnostics;
// ...
void SomeMethod() {
    Debug.WriteLine($"Dimensions are: {SomeDialog.DialogWidth:N2}x{SomeDialog.DialogHeight:N2}");
}

3. An exception of type InvalidCastException is thrown (see screenshots).

Expected behavior

No exception is raised, and the value is retrieved.

Additional context

Looking into the source code, this appears to be caused by an (allegedly) non-essential type cast.

In Dialog.cs, the DialogWidth and DialogHeight dependency properties are of type System.Double.

    /// <summary>
    /// Property for <see cref="DialogWidth"/>.
    /// </summary>
    public static readonly DependencyProperty DialogWidthProperty =
        DependencyProperty.Register(nameof(DialogWidth),
            typeof(double), typeof(Dialog), new PropertyMetadata(420.0));

    /// <summary>
    /// Property for <see cref="DialogHeight"/>.
    /// </summary>
    public static readonly DependencyProperty DialogHeightProperty =
        DependencyProperty.Register(nameof(DialogHeight),
            typeof(double), typeof(Dialog), new PropertyMetadata(200.0));

However, the property getters cast this value to System.Int32 before returning the result.

    /// <inheritdoc />
    public double DialogWidth
    {
        get => (int)GetValue(DialogWidthProperty);
        set => SetValue(DialogWidthProperty, value);
    }

    /// <inheritdoc />
    public double DialogHeight
    {
        get => (int)GetValue(DialogHeightProperty);
        set => SetValue(DialogHeightProperty, value);
    }

This last second cast to int may be what causes the InvalidCastException (as seen in the screenshot)

Start in src/Wpf.Ui/Controls/Dialog.cs and inspect the DialogWidth and DialogHeight dependency properties and their getters. Reproduce the XAML example on .NET 6/WPF-UI 2.0.2, retrieve both properties, and confirm the values are returned without InvalidCastException.
