Steps to reproduce the issue

• Create a top level category blog view.
• Create sub menu items under this menu item with same category but with tags filtering the category.
• Force Route::() with the top level menu item id. like this:
  $link = Route::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid, $this->item->language).'&Itemid=129');

Expected result

The article links inside the category blog view top level and submenu items to use itemid 129 for URL. So opening the items as if you are in the top level menu item. even when you are in one of the submenu items.

Actual result

In the submenu items it works fine. But the top level menu uses the last item in the submenu regardless of it being the highest menu item id. It takes sorting into account and just uses the last menu item id to build the link instead of the forced 129 (top level menu item)

System information (as much as possible)

Joomla 3.9.18
category blog layout override

Additional comments

even when not forcing a menu item id it still uses the last menu subitem to build the url.
attached a schematic of the menu how it is built to clarify stuff.
