GET request for a specific article returns "text" filed where intro text and full text are concatenated together

[MayaSima]

I need to automatically process fulltext from multiple articles. I pull the article, process fulltext, and then send it back via PATCH.
I noticed that "text" field in the GET request response contains both introtext and fulltext concatenated with "\r\n \r\n" like so:

`

Intro Text.

First Paragraph of full text.

`

As a result, I do the processing, publish the result back as a "fulltext", which results in intro text being copied to the full text and being duplicated on the updated page.

Steps to reproduce the issue

GET request to {{base_url}}/{{base_path}}/content/articles/{{article_id}}
parse the returned payload and retrieve "text" attribute
process
PATCH request wit hthe updated fulltext

Expected result

"fulltext" and "introtext" should be kept as separate fields in the response from GET request to {{base_url}}/{{base_path}}/content/articles/{{article_id}} endpoint

Not sure if "text" field is needed at all

Actual result

I receive "text" field with concatenated "introtext" + "fulltext" with no <hr id="system-readmore"> separator in between in the response from the GET request to {{base_url}}/{{base_path}}/content/articles/{{article_id}} endpoint

System information (as much as possible)

Joomla version 4.3.3
