Describe the bug

In Blazor templates with authentication enabled the whole top-row is clickable because the first anchor element fills the entire horizontal space.

This happens because of this style: https://github.com/dotnet/aspnetcore/blob/main/src/ProjectTemplates/Web.ProjectTemplates/content/ComponentsWebAssembly-CSharp/Client/Shared/MainLayout.razor.css#L72

Expected Behavior

Anchor tag should not be clickable outside its text.
