fix: FluentSelect does not update bind-Value in MAUI application

[JohnathanWaring]

🐛 Bug Report

FluentSelect does not update the @bind-Value in a .Net MAUI application.

💻 Repro or Code Sample

Create a .NET MAUI hybrid application Fluent UI template (v5.0.0-rc.4-26180.1), and paste the following into the Home.razor page:

@page "/"
@using MauiApp2.Shared.Services
@inject IFormFactor FormFactor

<PageTitle>Home</PageTitle>

<h1>Hello, world!</h1>

Welcome to your new Fluent app running on <em>@factor</em> using <em>@platform</em>.

<p>Selected EmployeeId: @EmployeeId</p>
<FluentSelect Placeholder="Select an item"
              Items="@employees"
              @bind-Value="EmployeeId"
              OptionText="@(item => $"{item.CreatedTime:yyyy-MM-dd} — {item.Name}")"
              OptionValue="@(item => item.Id)"
              Label="Employees" />

@code {
    class Employee
    {
        public string Id { get; set; }
        public string Name { get; set; }
        public DateTime CreatedTime { get; set; }
    }

    private List<Employee> employees = new List<Employee>
    {
        new Employee { Id = "1", Name = "Luke", CreatedTime = DateTime.Now },
        new Employee { Id = "2", Name = "Sarah", CreatedTime = DateTime.Now }
    };

    private string EmployeeId { get; set; } = string.Empty;
    private int Id { get; set; }

    private string factor => FormFactor.GetFormFactor();
    private string platform => FormFactor.GetPlatform();
}

Run the Maui application and navigate to the Home page, and select an option from the FluentSelect component..

🤔 Expected Behavior

FluentSelect should behave the same as the Web version.

😯 Current Behavior

When an option is selected, the variable bound to @bind-Value is not updated.

🌍 Your Environment

• OS & Device: Windows
• .NET: 10
• Fluent UI Blazor library Version: 5.0.0-rc.4-26180.1

I can't reproduce that with the latest bits (running locally). The Selected EmplyeeId shows and follows the selected item

Before

After

We will release RC 5 soon. Please retry it with that version once released and report back if you are still seeing the issue then.

Excellent, I'll give it a try when RC5 is ready. Thank you!
