Is this a bug or design choice?

versions: ci4 4.04 and ci4 4.x latest develop branch.

file: app/config/app.php

PHP Code:

public $indexPage = 'index.php'; 


Url that I'm currently in:

Code:

http://localhost:8080/index.php/books/add

when I try to echo current_url() in the view file. its returns,

Code:

http://localhost:8080/books/add

See! there is no index.php part in the URL. 

I think this is a bug. this method should return url with the index.php part.

In CI3 this was the default behaviour.
