Cancelled token does not prevent execution of ExecuteDeleteAsync(token)

Steps to reproduce

Following csproj and source code can be used to reproduce the issue.
ExecuteDeleteAsync send DELETE request to database even if cancellation already is requested by token.

public class Item

    public DateTimeOffset Date { get; set; }

public class ItemsDbContext: DbContext
{
    public ItemsDbContext(DbContextOptions options) : base(options) {}
    public DbSet<Item> Items { get; set; }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Item>().HasNoKey();
    }
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer("Data Source=(localdb)\\mssqllocaldb;Initial Catalog=Items;Integrated Security=True");
    }
}

var sp = new ServiceCollection()
    .AddDbContext<ItemsDbContext>()
    .BuildServiceProvider().CreateScope().ServiceProvider;
var ctx = sp.GetRequiredService<ItemsDbContext>();

using var cts = new CancellationTokenSource();
cts.Cancel();
count = await ctx.Items.Where(x => x.Date < DateTimeOffset.UtcNow).ExecuteDeleteAsync(cts.Token);
Console.WriteLine(count);

A proposed solution is to pass token taken from relational query context to call of IExecutionStrategy.ExecuteAsync(...)
