What is the mechanism for displaying a lead card in Bitrix24?

Question

Bitrix24

I know that the output goes through popup, but I would like more information.
Do I understand correctly that a document with the required lead opens in the browser, and where is it located?

{
                    BX.SidePanel.Instance.open("/crm/lead/details/0/?category_id=" + gridData.params.CATEGORY_ID);
                  }

Path to the script
Desktop-Content-Site structure-Files and folders-bitrix-js-crm-kanban-column.js

Just after opening the card, a new link to the main site is generated.
This is how it looks like in vianor_nv department
https://site/vianor_nv/company/personal/user/577/tasks/
And after opening the card, the link changes and leads to the main site
https://site/crm/lead/details/24084/

Let's start with the fact that this is not a popup, but a slider.
The technology of its work is not the same. This is stated in the slider documentation: https://dev.1c-bitrix.ru/api_help/js_lib/sidepanel... I quote
:

A slider is a sidebar that can open site pages in an iframe, as well as display arbitrary content within itself. The use of an iframe allows you to use ready-made components that work on regular site pages.
