`System.Windows.Forms.FlatStyle` doc falsely claims with `System` style the `TextAlign` is completely ignored

### Type of issue

Missing information

### Description

Documentation for the [FlatStyle Enum](https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.flatstyle?view=netframework-4.8.1) has following remark.

> If the System style is used, the appearance of the control is determined by the user's operating system and the following property values will be ignored: [Control.BackgroundImage](https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.control.backgroundimage?view=netframework-4.8.1), ImageAlign, Image, ImageIndex, ImageList, and TextAlign.

But at least on my machine (Windows 10, .NET 4.8) _only the **vertical** part_ of the alignment is ignored: `TopLeft`, `MiddleLeft`, and `BottomLeft` are all rendered as `TopLeft`; `TopCenter`, `MiddleCenter`, `BottomCenter` as `TopCenter`; `TopRight`, `MiddleRight`, `BottomRight` as `TopRight`.
