Longer item titles in the menu bar will be truncated with an ellipsis. This should be visible on the current leftmost breadcrumb item.
When you hit the current breadcrumb item (leftmost), the system will reload the content as well as the title with the latest text version.
The breadcrum list can be scrolled through in horizontal direction. Go ahead and try it with your pointer.
When you hit any item in the breadcrumb list, it will immediatelly go to that card and reload its content. You'll see a white flash for a split second, which indicates content refresh. Items to the left of the clicked item will be removed whereas items to the right will be preserved.
