TalkBack doesn't navigate to headings contained in StackLayout with a SemanticProperties.Description

Description

I needed to create a page containing multiple headings, so set SemanticProperties.HeadingLevel on particular labels. I also needed to create nested groupings with nesting that's accessible to screen readers, and in order to achieve this, I set SemanticProperties.Description on some StackLayouts. This worked well on Windows with the Narrator screen reader, and I mentioned how useful this was at https://twitter.com/gbarkerZ/status/1543533603921006592?s=20&t=cRkhQlhf4LSAISDmZZjFEQ.

I then built it and ran on Android, and found that the TalkBack screen reader apparently won't navigate to any headings that lie in a StackLayout with a SemanticProperties.Description. So the necessary navigation by headings doesn't work.

My version of .NET is 6.0.400-preview.22301.10,

Steps to Reproduce

1. Build and run an Android version of the app at https://github.com/gbarkerz/MyVeryFirstMauiApp. The code of interest is in https://github.com/gbarkerz/MyVeryFirstMauiApp/blob/master/MyVeryFirstMauiApp/MainPage.xaml.

2. Turn on the TalkBack screen reader on the Android device, set TalkBack's reading control to navigate by headings, and move forward through the headings in the app.

3. TalkBack moves through most headings in the app, but bypasses the heading that's contained in the StackLayout with the SemanticProperties.Description.

Based on further experiments, it seems that VoiceOver on Mac behaves the same way at the app as TalkBack does on Android, in that it bypasses headings contained in StackLayouts with a SemanticProperties.Description.
