Describe the bug

在表单中使用时，SelectObject总是出现必填星号
`@page "/"
@Attribute [TabItemOption(Text = "Index", Closable = false)]

    <div class="col-12">
        <Select @bind-Value="model.Icon" Items="_items">
        </Select>
    </div>

    <div class="col-12">
        <SelectObject @bind-Value="model.Icon" GetTextCallback="@(item => item)" Height="300"  DropdownMinWidth="300">
            <ListView  Items="@_items2">
                <BodyTemplate Context="value">
                    <Card>
                        <BodyTemplate>                                
                            <div class="lv-demo-desc">@value</div>
                        </BodyTemplate>
                    </Card>
                </BodyTemplate>
            </ListView>
        </SelectObject>
    </div>
</div>

@code {
private List _items=new List();
private List _items2=new List() { "a","b"};
private Model model = new Model();
class Model
{
public string Icon { get; set; }
}
}
`

Expected Behavior

SelectObject和SelectTable好像都有这个问题，属性未设置Required特性时仍然会出现必填星号
