Line similarity matching doesn't work well in some cases

[rg11175]

Step 0: Describe your environment

• OS: Windows11
• diff2html version: 3.4.22
• Using diff2html directly or using diff2html-ui helper: using diff2html-ui

Step 1: Describe the problem:

for some cases, the line similarity matching logic is not correct to my compared files, look at the example below:

You can see that diff2html has matched line number 7787 on the left with line number 7792 on the right, while I expect it to match line 7787 on the right with line 7791 on the left, the match as it currently stands is incorrect to me

here is my code:

`
const configuration: Diff2HtmlUIConfig = {
drawFileList: false,
fileListToggle: false,
fileListStartVisible: false,
outputFormat: 'side-by-side',
fileContentToggle: false,
renderNothingWhenEmpty: true,
matching: 'words',
matchWordsThreshold: 1,
stickyFileHeaders: true,
highlightLanguages: new Map<string, string>(),
// TBD: abap format - check with Yuri how to implement,
rawTemplates: {
'tag-file-changed': '',
'icon-file': '',
},
compiledTemplates: {
'generic-file-path': Hogan.compile(
'

{{ fileDiffName }}

'
) as Hogan.Template,
},
};

        const diffText = diff.createTwoFilesPatch(
          'file',
          'file',
          this.oldText,
          this.newText
        );

        const diff2htmlUi = new Diff2HtmlUI(
          targetElement,
          diffText,
          configuration
        );
        diff2htmlUi.draw();
        diff2htmlUi.highlightCode();
