Pull Request for Issue #40750 .

Summary of Changes

Only populate the menu items into $this->lookup if they are a direct match, or return_any_or_all is set to any.

Testing Instructions

Setup two tags.
Setup a menu item point to a singular tag
Setup a second menu item pointing to both tags, match type All
Populate articles into the first tag to show pagination within page (can change global config list limit to 5 to make this easier)
Navigate to the first menu item on the front end.
Observe pagination links

Pagination URL incorrectly pointing to second menu item (with multiple tags selected), instead of the current menu item.

Example: Page: /tag-1 pagination link: /tag-1?start=5

Expected result AFTER applying this Pull Request

Pagination URL's now correctly paginate through the current menu item.
