Notepads: Tabulation is wrong comparing to original Notepad

I also did a few tests, and seems like it’s really a bug in UWP SDK. Changing font family and font size doesn’t affect the first tabulation as well. I will try to write a bug report to Microsoft.

I think so. I changed SetDefaultTabStop

private void SetDefaultTabStop(FontFamily font, double fontSize)
{
    Document.DefaultTabStop = 200.0f;
    TextDocument.DefaultTabStop = 200.0f;
}

But it looks like the distance from 0->2 is the same as 2->3
