Describe the bug
The RadzenDataList component does not want to display the first load if the PageSize attribute is 10.
You can try putting 8,9,11,12,20, it all works. But number 10 does not work.

To Reproduce

<RadzenDataList AllowVirtualization="false"
				LoadData="@LoadDataV2"
				WrapItems="true"
				Data="@_testsDto" TItem="TestDto"
				AllowPaging=true
				PageSize=10
				Count="@_totalRows2">
	<Template Context="test">
		<RadzenColumn Size="10" class="rz-p-3">
			<RadzenText TextStyle="TextStyle.H5" TagName="TagName.H5" class="rz-color-secondary">@(test.Name)</RadzenText>
			</RadzenColumn>
		</Template>
	</RadzenDataList>

	@code {
	public class TestDto
	{
		public string Name { get; set; } = default!;
	}

	private List<TestDto> _testsDto = new();
	private int _totalRows2;

	public async Task LoadDataV2(LoadDataArgs args)
	{
		_testsDto = new List<TestDto>
		{
			new TestDto
			{
				Name = "test1"
			},
			new TestDto
			{
				Name = "test2"
			},
			new TestDto
			{
				Name = "test3"
			}
		};

		_totalRows2 = 3;
	}
}

Expected behavior

I don't know if this can help you, but I noticed during my tests that the function defined in the LoadData attribute is not being called.

Screenshots
With PageSize=10 (It's empty)

With PageSize=11
