backgroud service can't stop when use dotnet watch

[niltor]

Describe the bug

When I using dotnet run command or F5(with VS) to start the AspireHost, the migrations service can stop (The dashboard show Finished):

But when I using dotnet watch to run the AspireHost, the service still Running(Maybe stoped, but dashboard think as running):

Since other services will not start until the migration is completed, in this case, other services will never run.

The Console from terminal:

The console log from dashboard:

The code:

   protected override async Task ExecuteAsync(CancellationToken cancellationToken)
   {
       using var activity = _activitySource.StartActivity(
           "Migrating database",
           ActivityKind.Client
       );
       try
       {
           using var scope = serviceProvider.CreateScope();
           var dbContext = scope.ServiceProvider.GetRequiredService<DefaultDbContext>();

           await RunMigrationAsync(dbContext, cancellationToken);
           await SeedDataAsync(dbContext, cancellationToken);
       }
       catch (Exception ex)
       {
           activity?.AddException(ex);
           throw;
       }
       hostApplicationLifetime.StopApplication();
   }

Expected Behavior

migrations service should stopped as normal when using dotnet watch.

Steps To Reproduce

using the dotnet watch to start aspire host.

It is very easy to reproduce; I created a default aspire template project and added a migrations project.
