AspNetCore `net8.0` - Blazor {*CatchAll} route overrides MVC AdminController route

I'm using a Blazor8 with OrchardCore as a de-coupled CMS. I want /admin* to be routed by Orchard, and the rest to be routed by Blazor. Using this as a basic working example: https://github.com/ApacheTech/BlazOrchard If I have a page with @page "/{*Slug}";, I want to give priority to /admin to run through the MVC Area controller. It seems that Blazor strips all power away from MVC to route itself. I want Blazor to be the fallback.

There is no manual mapping here, other than Blazor. Would I need to map the admin area separately. If so, in which part?

using BlazOrchard.BlazorWebApp.Components;
using OrchardCore.Logging;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Host.UseNLogHost();
builder.Services
    .AddOrchardCms()
    .ConfigureServices(services =>
    {
        services.AddRazorComponents()
            .AddInteractiveServerComponents()
            .AddInteractiveWebAssemblyComponents();
    })
    .Configure((app, routes, _) =>
    {
        app.UseStaticFiles();
        app.UseAntiforgery();
        routes.MapRazorComponents<App>()
            .AddInteractiveServerRenderMode()
            .AddInteractiveWebAssemblyRenderMode()
            .AddAdditionalAssemblies(typeof(BlazOrchard.BlazorWebApp.Client._Imports).Assembly);
    })
    ;

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseWebAssemblyDebugging();
}
else
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseOrchardCore();
app.Run();

using BlazOrchard.BlazorWebApp.Components;
using OrchardCore.Logging;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Host.UseNLogHost();
builder.Services
    .AddOrchardCms()
    .ConfigureServices(services =>
    {
        services.AddRazorComponents()
            .AddInteractiveServerComponents()
            .AddInteractiveWebAssemblyComponents();
    })
    .Configure((app, routes, _) =>
    {
        app.UseStaticFiles();
        app.UseAntiforgery();
        routes.MapRazorComponents<App>()
            .AddInteractiveServerRenderMode()
            .AddInteractiveWebAssemblyRenderMode()
            .AddAdditionalAssemblies(typeof(BlazOrchard.BlazorWebApp.Client._Imports).Assembly);
    })
    ;

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseWebAssemblyDebugging();
}
else
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    app.UseHsts();

app.UseHttpsRedirection();

This is the page I would like to have work.

@page "/{*Slug}";
@if(_contentItem is null)
{
    <StatusCodeErrorPage StatusCode="@(404)" />
}
else
{
    <DynamicComponent Type="_contentItemType" Parameters="_parameters" />
}

@code {
    private Dictionary<string, object> _parameters = [];
    private ContentItem? _contentItem;
    private Type? _contentItemType;

    [Parameter]
    public string Slug { get; set; }

    [Inject]
    private IOrchardHelper Orchard { get; init; }

    protected override async Task OnParametersSetAsync()
    {
        _contentItem = await Orchard.GetContentItemBySlugAsync(Slug);
        if (_contentItem is null) return;
        _parameters["ContentItem"] = _contentItem;
        _contentItemType = GetType().Assembly
            .GetTypes()
            .Where(p => !p.IsAbstract && p.IsSubclassOf(typeof(CsmHostedComponentBase)))
            .SingleOrDefault(p => p.Name == _contentItem.ContentType);
        StateHasChanged();
    }
}

@page "/{*Slug}";
@if(_contentItem is null)
{
    <StatusCodeErrorPage StatusCode="@(404)" />
}
else
{
    <DynamicComponent Type="_contentItemType" Parameters="_parameters" />
}

@code {
    private Dictionary<string, object> _parameters = [];
    private ContentItem? _contentItem;
    private Type? _contentItemType;

    [Parameter]
    public string Slug { get; set; }

    [Inject]
    private IOrchardHelper Orchard { get; init; }

    protected override async Task OnParametersSetAsync()
    {
        _contentItem = await Orchard.GetContentItemBySlugAsync(Slug);
        if (_contentItem is null) return;
        _parameters["ContentItem"] = _contentItem;
        _contentItemType = GetType().Assembly
            .GetTypes()
            .Where(p => !p.IsAbstract && p.IsSubclassOf(typeof(CsmHostedComponentBase)))
            .SingleOrDefault(p => p.Name == _contentItem.ContentType);
        StateHasChanged();
    }
}

Then all my components would be at /Components/ContentTypes/{nameof(ContentType)}.razor, and inherit from CmsHostedComponentBase that supplies access to the helper, and other injected tools, as standard. But, using this, calls to /admin result in the 404 component showing. MVC is ignored. I thought that catch-all routes were supposed to have lowest priority.
