Select not working with CultureInfo en-GB on .NET MAUI blazor hybrid

[bpsc-wkubis]

🐛 Bug Report

I am attempting to implement FluentSelect as a culture picker in my Blazor Hybrid Maui application. Previously, I utilized an HTML select, which functioned correctly in all scenarios

@page "/"
@using System.Globalization


<h1>@Resources.Resource1.HelloWorld</h1>


<strong>Culture:</strong>
<select @bind="Culture">
    @foreach (var culture in cultures)
    {
        <option value="@culture">@culture.DisplayName</option>
    }
</select>

@code
{
    CultureInfo[] cultures = new[]
    {
        new CultureInfo("en-GB"),
        new CultureInfo("pl-PL")
    };

    CultureInfo Culture
    {
        get => CultureInfo.CurrentCulture;
        set
        {
            if (CultureInfo.CurrentCulture != value)
            {
                Thread.CurrentThread.CurrentCulture = value;
                Thread.CurrentThread.CurrentUICulture = value;
                CultureInfo.DefaultThreadCurrentCulture = value;
                CultureInfo.DefaultThreadCurrentUICulture = value;
            }
        }
    }
}

However, when I replace the HTML select with FluentUI select, I encounter issues when one of the available cultures is set to "en-GB". It appears as though the FluentUI select is caught in an infinite loop within the setter of the Culture property, when I switch the culture to "en-US", the FluentUI select operates as expected.

@page "/"
@using System.Globalization


<h1>@Resources.Resource1.HelloWorld</h1>

<FluentSelect 
    Items="@cultures" 
    @bind-SelectedOption="Culture">
</FluentSelect>

@code
{
    CultureInfo[] cultures = new[]
    {
        new CultureInfo("en-GB"), // Only breaks on en-GB - en-US works fine
        new CultureInfo("pl-PL")
    };

    CultureInfo Culture
    {
        get => CultureInfo.CurrentCulture;
        set
        {
            if (CultureInfo.CurrentCulture != value)
            {
                Thread.CurrentThread.CurrentCulture = value;
                Thread.CurrentThread.CurrentUICulture = value;
                CultureInfo.DefaultThreadCurrentCulture = value;
                CultureInfo.DefaultThreadCurrentUICulture = value;
            }
        }
    }
}

It's strange, but it doesn't seem to come from a particular culture, but from the lack of "Default Culture" in the list of proposals. Is this possible?

In any case, adding CultureInfo.CurrentCulture works for me.

CultureInfo[] cultures = new[]
{
    CultureInfo.CurrentCulture, // 👈
    new CultureInfo("en-GB"), 
    new CultureInfo("pl-PL"),
};

Thank for feedback, this workaround is sufficient for me, I will leave it up to you if you wanna change this behavior or leave it as it is.
