### Describe the bug

I'm using .NET 6 and razor pages.
```[PageRemote]``` attribute in ```POST``` method doesn't send ```__requestverificationtoken``` to server and I get error 400.

### Expected Behavior

```PageRemote``` attribute doesn't work and doesn't send ```__requestverificationtoken``` filed on post method.
This is my ViewModel
```
public class AddCategory
{
[PageRemote(PageName = "Category", PageHandler = "CheckForTitle",
HttpMethod = "POST",
AdditionalFields = "__RequestVerificationToken",
ErrorMessage = "This title is duplicate")]
public string Title { get; set; } = null!;
}
```
And this is my handler
```
public class CategoryModel : PageModel
{
[BindProperty]
public AddCategory Category { get; set; }

public void OnGet()
{
}

public IActionResult OnPostCheckTitle(AddCategory category)
{
return new JsonResult(category.Title == "a");
}
}
```
```GET``` method is ok and everything is fine, but in ```POST``` method ```__requestverificationtoken``` doesn't send to the server and I get error 400.
