Built a combobox setter that opened the picklist, read options, and clicked the match in ONE synchronous JS call — it found no options ("option not found", available:[]). Lightning renders the option list ~600ms AFTER the trigger click. Fix: split into open -> wait ~0.7s -> pickOption (the shipped __bh_openCombo/__bh_pickOption pair).
