TabViewItem does not respect theme resource TabViewItemHeaderForeground

[Felix-Dev]

Describe the bug
Changing the theme resource TabViewItemHeaderForeground does not change the foreground of the TabViewItem's header as expected. See this XAML:

<muxc:TabView>
    <muxc:TabView.Resources>
        <SolidColorBrush x:Key="TabViewItemHeaderForeground" Color="Green" />
        <SolidColorBrush x:Key="TabViewItemHeaderForegroundSelected" Color="LightGreen" />
    </muxc:TabView.Resources>
</muxc:TabView>

The look we get is this:

Expected behavior

NuGet package version:
Microsoft.UI.Xaml v2.4.0-prerelease.200422001

Additional context
I would like to fix this.
