Description

@JimBobSquarePants Wish I could say I hadn't found another bug in the latest version of Fonts, but, see Steps to Reproduce...

Steps to Reproduce

using System.Numerics;
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.Drawing.Processing;
using SixLabors.ImageSharp.PixelFormats;
using SixLabors.ImageSharp.Processing;
using SixLabors.Fonts;

namespace TextRunTest;

internal class Program {
	static void Main(string[] args) {
		Console.WriteLine("Rendering test images...");
		//test1();
		//test2();
		test3();

		Console.WriteLine("Done.");
	}

	private static void test3() {
		var fontManager = new FontManager();
		
		string text1 = "⇒ Tim Cook\n⇒ Jef Bezos\n⇒ Steve Jobs\n⇒ Mark Zuckerberg";
		string text2 = "⇒ Tim Cook\n⇒ Jeff Bezos\n⇒ Steve Jobs\n⇒ Mark Zuckerberg";
		var renderingFont = fontManager.GetFont("Charis SIL", 85, FontStyle.Bold);
		var options = new RichTextOptions(renderingFont) {
			Origin = new Vector2(50, 20),
			LayoutMode = LayoutMode.HorizontalTopBottom,
			VerticalAlignment = VerticalAlignment.Top,
			TextAlignment = TextAlignment.Start,
			WrappingLength = 860,
		};

		Image imgTest3 = new Image<Rgba32>(1100, 500, Color.White);
		imgTest3.Mutate(x =>
			x.DrawText(options, text1, Color.Black)
		);
		imgTest3.SaveAsPng("c:/development/diff/testImg1.png");
		// ^ renders normally

		Image imgTest4 = new Image<Rgba32>(1100, 500, Color.White);
		imgTest4.Mutate(x =>
			x.DrawText(options, text2, Color.Black)
		);
		imgTest4.SaveAsPng("c:/development/diff/testImg2.png");
		// ^ causes 4th line to disappear...?
	}
}

I can’t keep doing releases like this. If you have tests please supply them all.

@jez9999 I just reread what I wrote there, and I realised it might have come across wrong; I'm frustrated at myself not you. You've been incredibly helpful!

I don't have tests, I just have software that I use regularly which renders stuff with Imagesharp and I happen to come across the bugs.
