FontNameEditor rendering artifact - *just* the blue box

Problem description:

FontNameEditor font preview is showing less characters. For example on the below screenshots:

Font	.NET 4.7.2	.NET Core 3.0
Arial Black	ab	a
Forte	abc	ab
Lucida Handwriting	ab	a

Actual behavior:

.NET 4.7.2	.NET Core 3.0

🤔 ink It is possible the change may related to the change of the default font in #656.

Expected behavior:

We show the same amount of characters as with .NET FX.

It looks like we can achieve the same render by reducing the fontSize in DrawFontSample:

        private static void DrawFontSample(PaintValueEventArgs e, FontFamily fontFamily, FontStyle fontStyle)
        {
            float fontSize = (float)(e.Bounds.Height / 1.2);
            using (var font = new Font(fontFamily, fontSize, fontStyle, GraphicsUnit.Pixel))
            {
                e.Graphics.DrawString("abcd", font, SystemBrushes.ActiveCaptionText, e.Bounds);
            }
        }

Minimal repro:

• Run WinformsControlsTest in .NET 4.7.2 and .NET 3
• Compare

😄 Yes, just the blue box.

We’re going to take a fix here. It looks like it happens both in Framework and in Core and per @RussKie the implementation looks like just a line being added, with no particular purpose.
