// Remove the tab root (parent) if the current path links to its parent.
// Normally, the tab root link is included in the breadcrumb, as soon as we
// are on a local task or any other child link. However, if we are on a
// default local task (e.g., node/%/view), then we do not want the tab root
// link (e.g., node/%) to appear, as it would be identical to the current
// page. Since this behavior also needs to work recursively (i.e., on
// default local tasks of default local tasks), and since the last non-task
// link in the trail is used as page title (see menu_get_active_title()),
// this condition cannot be cleanly integrated into menu_get_active_trail().
// menu_get_active_trail() already skips all links that link to their parent
// (commonly MENU_DEFAULT_LOCAL_TASK). In order to also hide the parent link
// itself, we always remove the last link in the trail, if the current
// router item links to its parent.
if (($item['type'] & MENU_LINKS_TO_PARENT) == MENU_LINKS_TO_PARENT) {
array_pop($active_trail);
