Describe the bug

I made a brand new .NET 6 project with VS22, I added Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation package from NuGet, then I have in the Program.cs

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllersWithViews().AddRazorRuntimeCompilation();

and the layout of Bootstrap "crashes": the footer is no more fixed to the bottom of the page, the header doesn't have the shadow anymore and so on. It follows a screenshot of the crashed page:
