Joomla has a problem with search-friendly URLs. Path in links is not correctly converted from NON-Friendly links to search-friendly links. The problem only appears when an article is nested in the sub-category.

Steps to reproduce the issue

Settings:

• Global Configuration -> Site -> SEO Settings -> Search Engine Friendly URLs -> YES
• Global Configuration -> Site -> SEO Settings -> Use URL Rewriting -> YES
• Global Configuration -> Site -> SEO Settings -> Add Suffix to URL -> NO
• Global Configuration -> Site -> SEO Settings -> Unicode Aliases -> NO
• Article: Options -> Integration -> URL Routing -> Modern
• Article: Options -> Integration -> Remove ID from URLs -> YES

How to reproduce:

1. Create the category "blog".
2. Create additional 2 categories. One as the main category ("MainCategory") and the second one as a sub-category ("SubCategory").
3. Create a test article (alias of the article: "test-article") into the "SubCategory".
4. Create the article (alias of the article: "blog-article") in the blog category. Create a link in the content of the article to the test article to the "SubCategory". Structure the link as follows (index.php?option=com_content&view=article&id=22:test-article&catid=15), use appropriate IDs in link for article and category.
5. Add menu item as "Category Blog" to category "Blog".
6. Test it; the link in the blog article is broken.

Expected result

https://www.example.com/MainCategory/SubCategory/test-article

Actual result

Link in blog article
https://www.example.com/blog/test-article
