When I assign an Id to a FormGroup in TelerikForm, it's value can be seen in code, but neither the attribute nor it's value get rendered.
<TelerikForm Model="@TestUser"
OnValidSubmit="@HandleValidSubmit"
OnInvalidSubmit="@HandleInvalidSubmit">
<FormValidation>
<DataAnnotationsValidator></DataAnnotationsValidator>
</FormValidation>
<FormItems>
<FormGroup LabelText="User Information" Id="userinfo">
<FormItem Field="@nameof(User.FirstName)"></FormItem>
<FormItem Field="@nameof(User.LastName)"></FormItem>
<FormItem Field="@nameof(User.Email)">
<Template>
<label for="mail" class="k-label k-form-label">Email*:</label>
<TelerikTextBox Id="mail" @bind-Value="@TestUser.Email" InputMode="email" Placeholder="example@domain.com"></TelerikTextBox>
<TelerikValidationMessage For="@(() => TestUser.Email)"></TelerikValidationMessage>
</Template>
</FormItem>
<FormItem Field="@nameof(User.Password)">
<Template>
<label for="pass" class="k-label k-form-label">Password*:</label>
<TelerikTextBox Id="pass" @bind-Value="@TestUser.Password" Password="true"></TelerikTextBox>
<TelerikValidationMessage For="@(() => TestUser.Password)"></TelerikValidationMessage>
</Template>
</FormItem>
<FormItem Field="@nameof(User.BirthDate)" />
<FormItem Field="@nameof(User.AcceptTerms)" />
</FormGroup>
<FormGroup LabelText="Shipping Address" Id="shipaddress">
<FormItem LabelText="Country*: " Field="@nameof(User.Country)" />
<FormItem LabelText="City*: " Field="@nameof(User.City)" />
<FormItem LabelText="Address Line*: " Field="@nameof(User.AddressLine)" />
<FormItem LabelText="Second Address Line: " Field="@nameof(User.AddressLine2)" />
</FormGroup>
</FormItems>
</TelerikForm>
