Pretty print whitespace handling should be stable

With jsoup 1.15.4 I get strange results when parsing a document again and again;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Entities;
import org.junit.jupiter.api.Test;

import java.nio.charset.StandardCharsets;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class JsoupTest {


    @Test
    public void test() {
        var text = """
                <div>
                        <a> <b>Hello</b> </a>
                </div>""";
        var os = (new Document.OutputSettings())
                .syntax(Document.OutputSettings.Syntax.html)
                .indentAmount(2)
                .charset(StandardCharsets.UTF_8)
                .escapeMode(Entities.EscapeMode.base)
                .prettyPrint(true)
                .outline(false);
        String text1 = Jsoup.parse(text).body().html();
        String text2 = Jsoup.parse(text1).outputSettings(os).body().html();
        String text3 = Jsoup.parse(text2).outputSettings(os).body().html();
        String text4 = Jsoup.parse(text3).outputSettings(os).body().html();
        System.out.println(text1 + "\n");
        System.out.println(text2 + "\n");
        System.out.println(text3 + "\n");
        System.out.println(text4 + "\n");
        assertEquals(text3, text4);
    }
}

This test fails. And IMHO it shouldn't

The output is

<div><a> <b>Hello</b> </a>
</div>

<div>
  <a> <b>Hello</b> </a>
</div>

<div><a> <b>Hello</b> </a>
</div>

<div>
  <a> <b>Hello</b> </a>
</div>

Hi, thanks for the clear report. This is fixed already in the upcoming 1.16.1 release. I've made a few fixes but I think it would be #1906.

The output now is:

<div>
 <a> <b>Hello</b> </a>
</div>

<div>
  <a> <b>Hello</b> </a>
</div>

<div>
  <a> <b>Hello</b> </a>
</div>

<div>
  <a> <b>Hello</b> </a>
</div>
