Not related to rendermode

I have a Blazor .NET 8 application with a parent component (Edit.razor) that contains an EditForm and a child component (ButtonTest) within it. The parent component’s OnInitializedAsync method calls an async method (GetModel) to retrieve data. However, I’ve noticed that the OnInitializedAsync method of the child component (ButtonTest) is being called twice.
Here’s a simplified version of my code:

Edit.razor:

@page "/Edit"
@rendermode @(new InteractiveServerRenderMode(false))

@if (Model != null)
{
    <EditForm Model="@Model">
        <ButtonTest></ButtonTest>
    </EditForm>
}

@code {

    private string Model { get; set; } = string.Empty;

    protected override async Task OnInitializedAsync()
    {
        Model = await GetModel();
        await base.OnInitializedAsync();
    }

    private async Task<string> GetModel()
    {
        await Task.Delay(1);
        return "Hello world";
    }
}

ButtonTest.razor:

<h3>ButtonTest</h3>

@code {
    protected override Task OnInitializedAsync()
    {
        return base.OnInitializedAsync();
    }
}

In this setup, when GetModel is called within the OnInitializedAsync of the parent component, the OnInitializedAsync method of the child component (ButtonTest) is triggered twice.

I’m curious about why this is happening and how I can prevent it. Any insights or suggestions would be greatly appreciated. Thank you!
