Possible Bug? Or possibly I have something misconfigured? I am using Visual Studio 2022 version 17.9.0 and I created a Blazor Server App (interactive rendering mode/Global) and the visual appearance of the tabs differs greatly from your documentation. 17.8.7 had the same issue. If I create a project in Blazor Server 7 the tabs appear as they do in your documentation site.
Attached are the different appearances for the two version:
edit: blazor 7 (the good version) is the top image, the bottom image is the blazor 8.
