hilight_parent_pins(): if two or more child pins are attached to the same parent net hilighting one of these child pins will not propagate to parent if the unhilight child pin comes after the hilight pin. This is now fixed. Going up in hierarchy will never clear parent hilights. It is recommended to clear all probes before tracking child pin propagation with hilights upstream.
