关于Checkboxlist 选项bug问题

[AshWang-whm]

Describe the bug

有个checkboxlist的问题，我这样给Items赋值时，会出现需要双击才能选中Checkbox，而且只能单选了， 改成razor中声明的List TestItems是无问题的，radiolist和multicselect不会出现这个问题
将下面代码 替换原 BootstrapBlazor.Share.Page.Index.razor 可以复现

code

@layout HomeLayout
@page "/"
@page "/index"
@page "/home"

@{
foreach (var field in FormGen.FormFields)
{
RenderFragment render = null;
switch (field.formFieldType)
{
case FormFieldType.TextBox:
render =@<BootstrapInput DisplayText="@field.Name" ShowLabel="true" TValue="string" @bind-Value="@field.Value"/>;
break;
case FormFieldType.MulticSelecte:
render =@<MultiSelect DisplayText="@field.Name" ShowLabel="true" Items="@field.Selecteds" TValue="string" @bind-Value="@field.Value"/>;
break;
case FormFieldType.Radio:
render =@<RadioList DisplayText="@field.Name" ShowLabel="true" Items="@field.Selecteds" TValue="string" @bind-Value="@field.Value"/>;
break;
case FormFieldType.CheckBox:
render = @<CheckboxList DisplayText="@field.Name" @ref="@testCheckBox" ShowLabel="true" Items="@field.Selecteds" TValue="string" @bind-Value="@field.Value"/>;
break;
}

@render

}



}
@
<CheckboxList @bind-Value="@teststr" DisplayText="测试" ShowLabel="true" Items="TestItems"/>
