Describe the bug
When using a record type instead of a class in a Razen Template Form, when the form is dirty (Ie text added), and before the user clicks out of the input field, it is required to press submit twice.

To Reproduce
Steps to reproduce the behavior:

The example code below demonstrates the difference between using a record and a class.

<RadzenTemplateForm TItem="RecordModel" Data="@_recordModel" Submit="@OnRecordSubmit">
    <RadzenTextBox @bind-Value="@_recordModel.FirstName" />
    <RadzenButton ButtonType="ButtonType.Submit" Icon="save" Text="Submit"></RadzenButton>
</RadzenTemplateForm>

<RadzenTemplateForm TItem="ClassModel" Data="@_classModel" Submit="@OnClassSubmit">
    <RadzenTextBox @bind-Value="@_classModel.FirstName" />
    <RadzenButton ButtonType="ButtonType.Submit" Icon="save" Text="Submit"></RadzenButton>
</RadzenTemplateForm>

@code {
    record RecordModel
    {
        public string FirstName { get; set; }
    }

    class ClassModel
    {
        public string FirstName { get; set; }
    }
    
    private RecordModel _recordModel = new RecordModel();
    private ClassModel _classModel = new ClassModel();


    void OnRecordSubmit()
    {
        //Put breakpoint here
    }


    private void OnClassSubmit()
    {
        //Put breakpoint here
    }
}

Start typing in the text field and click submit before leaving the focus on the textbox.

If you lose focus before clicking submit it submits the first time.

I pushed an attempted fix but I am not 100% sure it addresses the issue 1398e54896

Sometimes it worked without the fix, other it didn't. You can try pulling the master branch and testing in your application. The provided demo seems to work always with this fix applied.
