Avoid hierarchal (tree) structure in the textlayer of pdfjs

I have been using Pdfjs for quite a long but with the recent update started to face issues with the textlayer structure. Previously the textlayer was flattened but with the latest release textlayer started to have hierarchy (tree) structure.
Previous version Example:(2.8)

<div id="textlayer">
<span>Hello World !!!</span>
<span>I'm confused </span>
</div>

Latest version Example:(2.14)

<div id="textlayer">
<span>
<br>
<span>Hello World !!!</span>
</span>
<span>
<br>
<br>
<span>I'm confused</span>
</span>
</div>

any way to get a flat structure on the textlayer?

https://cdn.jsdelivr.net/npm/pdfjs-dist@2.14.305/web/pdf_viewer.js

That version is no longer supported, please find the latest releases at https://mozilla.github.io/pdf.js/getting_started/#download

is there any way to achieve this without changing in the pdf viewer file

Unfortunately not, since various other parts of the default viewer uses that to improve accessibility.

When opening an issue, please provide all of the information requested in https://github.com/mozilla/pdf.js/blob/master/.github/ISSUE_TEMPLATE.md since as-is this issue unfortunately isn’t really possible to easily understand/reproduce. Of particular importance is that you provide the PDF document in question.

It’s possible that you’ll need to use the includeMarkedContent parameter, however it is off by default, see https://github.com/mozilla/pdf.js/blob/8bad06f1580f8235c0ab4038d9211587dd39a9b5/src/display/api.js#L1078-L1085 and https://github.com/mozilla/pdf.js/blob/8bad06f1580f8235c0ab4038d9211587dd39a9b5/src/display/api.js#L1643-L1651
