Attribute name="" from Input* when included, the data from form cannot be submitted.

Describe the bug

The name="" attribute specified within the <Input*> element seems to disrupt the form submission behavior upon clicking the submit button.

Expected Behavior

Expected behaviour is the name="" should not have any effect when submitting.

Steps To Reproduce

This issue can be reproduced by integrating the provided code snippet into a new Blazor project and replacing the contents of the counter.razor file.

@page "/counter"

<EditForm Model="Model" OnSubmit="Submit" FormName="Form1" Enhance>
    <div class="mb-3">
        <label for="name" class="form-label">Recipe Name</label>
        <InputText @bind-Value="Model!.Name" class="form-control" id="name" name="something"/>
    </div>
    <button type="submit" >Submit</button>
</EditForm>

@code {
    [SupplyParameterFromForm] 
    public Starship? Model { get; set; } = new();

    protected override void OnInitialized()
    {
        Model!.Name ??= "init value";
    }

    private void Submit()
    {
        Console.WriteLine($"Name: {Model!.Name}");
    }

    public class Starship
    {
        public int Id { get; set; }
        public string? Name { get; set; }
    }
}

The inclusion of the name="something" attribute within the component appears to be the cause of this behavior. Upon removing this attribute, the form submission resumes normal functionality.
