Blazor Hybrid templates have an empty title bar

[Eilon]

The default Blazor Hybrid templates have an empty window title bar. The regular .NET MAUI templates have the app's name in the title bar.

Blazor Hybrid, even if I set the ContentPage's Title	.NET MAUI
Taskbar (no title)	Taskbar (has title)

I'm not sure the right way to fix this. It seems that the Shell control picks up the title and makes it the app window's title. But without Shell I'm not sure how to do it.

Looks like its this:

maui/src/Controls/src/Core/Window/Window.cs

Line 110 in f86bf47

string? ITitledElement.Title => Title ?? (Page as Shell)?.Title;

We only cast it to Shell and take that title, but don't do it for any other page type?

The other thing we could to is set the title in the App.xaml.cs when we create a new window but I don't think that's a great solution as you'll have another separate place where you need to set a title.

Added a potential fix here: #25338 lets try the resulting binaries and see if that has the desired effect. Also cc: @PureWeen

Verified this works, see PR.

All shell does it set it on the Window

The guidance here for users has been to just set it on the Window itself

every element in the hierarchy has access to the window so it can set it that way.

Now that we make people override CreateWindow you can set it there
