Styling Hight of Shell.TitleView

I am missing some documentation how to style the top of the shell page.
Even when setting an Shell.TitleView with a tiny label the header of the page continues to be higher.
It seems there must be some container around the Shell.TitleView and ShellToolbar that can not by styled.

```

```

Below image show tiny label "Main" - but the top area (black part) continues to stay much higher. This is on a out of the box MAUI template.
