Code before:
using Microsoft.JSInterop;

namespace Microsoft.AspNetCore.Components.QuickGrid.Test;

public class GridRaceConditionTest
{
    private TestRenderer _renderer = new();
    private TaskCompletionSource _tcs = new();

    public GridRaceConditionTest()
    {
        var testJsRuntime = new TestJsRuntime(_tcs);
        var serviceProvider = new ServiceCollection()
            .AddSingleton<IJSRuntime>(testJsRuntime)
            .BuildServiceProvider();
        _renderer = new(serviceProvider);
    }

    [Fact]
    public async Task CanCorrectlyDisposeAsync()
    {
        var testComponent = new TestComponent();

        var componentId = _renderer.AssignRootComponentId(testComponent);
        _renderer.RenderRootComponent(componentId);
        await Task.Delay(10);
        _renderer.RenderRootComponent(componentId);
        _tcs.SetResult();
    }
}

internal class TestComponent : ComponentBase
{
    private bool _firstRender = true;
    private PaginationState _pagination = new() { ItemsPerPage = 2 };

    internal class Person
    {
        public int Id { get; set; }
        public string Name { get; set; } = string.Empty;
        public int Age { get; set; }
    }

    private IQueryable<Person> _people = new List<Person>
    {
        new Person { Id = 1, Name = "John Doe", Age = 30 },
        new Person { Id = 2, Name = "Jane Smith", Age = 25 },
        new Person { Id = 3, Name = "Alice Johnson", Age = 22 }
    }.AsQueryable();

    protected override void BuildRenderTree(RenderTreeBuilder builder)

Review comment (bug):
Will this work with only `await Task.Yield()`? In the meaning: would the test fail consistently without the change from `src/Components/QuickGrid/Microsoft.AspNetCore.Components.QuickGrid/src/QuickGrid.razor.cs` if we remove the delay? Each delay prolongs the execution of the test suite, I'm looking for a way to avoid it.

Code after:
using Xunit.Sdk;

namespace Microsoft.AspNetCore.Components.QuickGrid.Tests;

public class GridRaceConditionTest
{

    [Fact]
    public async Task CanCorrectlyDisposeAsync()
    {
        var moduleLoadCompletion = new TaskCompletionSource();
        var moduleImportStarted = new TaskCompletionSource();
        var testJsRuntime = new TestJsRuntime(moduleLoadCompletion, moduleImportStarted);
        var serviceProvider = new ServiceCollection()
            .AddSingleton<IJSRuntime>(testJsRuntime)
            .BuildServiceProvider();
        var renderer = new TestRenderer(serviceProvider);

        var testComponent = new SimpleTestComponent();

        var componentId = renderer.AssignRootComponentId(testComponent);
        renderer.RenderRootComponent(componentId);

        // Wait until JS import has started but not completed
        await moduleImportStarted.Task;

        // Dispose component while JS module loading is pending
        testJsRuntime.MarkDisposed();
        await renderer.DisposeAsync();

        // Complete the JS module loading
        moduleLoadCompletion.SetResult();

        // Wait until after OnAfterRenderAsync has completed to test the disposal of the jsModule
        var notFailingGrid = testComponent.NotFailingGrid;
        await notFailingGrid.OnAfterRenderCompleted;

        // Assert that init was not called after disposal and JsModule was disposed of
        Assert.False(testJsRuntime.InitWasCalledAfterDisposal,
            "Init should not be called on a disposed component.");
        Assert.True(testJsRuntime.JsModuleDisposed);
    }

    [Fact]
    public async Task FailingQuickGridCallsInitAfterDisposal()
    {
        var moduleLoadCompletion = new TaskCompletionSource();
        var moduleImportStarted = new TaskCompletionSource();
        var testJsRuntime = new TestJsRuntime(moduleLoadCompletion, moduleImportStarted);
        var serviceProvider = new ServiceCollection()
            .AddSingleton<IJSRuntime>(testJsRuntime)
