You're right; I believe that they recently clarified some pedestrian ROW issues: note 2), below.
RCW 46.61.235 Crosswalks.
(1) The operator of an approaching vehicle shall stop and remain stopped to allow a pedestrian or bicycle to cross the roadway within an unmarked or marked crosswalk when the pedestrian or bicycle is upon or within one lane of the half of the roadway upon which the vehicle is traveling or onto which it is turning. For purposes of this section "half of the roadway" means all traffic lanes carrying traffic in one direction of travel, and includes the entire width of a one-way roadway. (2) No pedestrian or bicycle shall suddenly leave a curb or other place of safety and walk, run, or otherwise move into the path of a vehicle which is so close that it is impossible for the driver to stop. (3) Subsection (1) of this section does not apply under the conditions stated in RCW 46.61.240(2). (4) Whenever any vehicle is stopped at a marked crosswalk or at any unmarked crosswalk at an intersection to permit a pedestrian or bicycle to cross the roadway, the driver of any other vehicle approaching from the rear shall not overtake and pbutt such stopped vehicle.
