precise
Records the DOWN position of each touch into state, mirroring COUI PreciseClickHelper's OnTouchListener. Attach to the anchor of a popup that was given the same PreciseClickState so the popup opens at the finger.
The handler observes in PointerEventPass.Initial and consumes nothing, so the anchor's own clickable still sees the whole gesture; accessibility clicks produce no pointer event at all and therefore leave the point unrecorded, which is exactly COUI's TalkBack fallback.
