Menu Active Trail Deepest
This module enhances Drupal's menu system by ensuring the deepest possible menu item is marked as active when multiple items point to the same path. It corrects a behavior where Drupal core often only highlights a parent menu item, even when a child item also matches the current URL.
Uses the deepest matching menu link for the active trail, instead of current Drupal behavior where just the parent item gets the active trail even if it has children also pointing to the current path.

Features
Consider you have this kind of menu:
item A linking to path 1
-- item B linking to path 1
---- item C linking to path 1
---- item D linking to path 2
-- item E linking to path 3
Clicking on item A, item B or item C will bring user to the same path 1. As item A and item B are just parent containers of item C, item C should be the active link. However Drupal core shows item A as the active link, ignoring item B and item C. This is what this module solves..
Just install the module and all menu items matching current path will get the active trail.
