menu_active_trail_deepest

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.

Solves this Drupal core issue: https://www.drupal.org/node/732370

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.
