Remove the knobRect override: native slider geometry also affects drag positioning. Progress pointer tracking now shares the drawn thumb bounds, preserves the initial grab offset, and clamps to the track endpoints. Expanded native event regression covers adjacent clicks, thumb drags, track drags, and endpoint clamping; application build passes.
The 3-point progress thumb was drawn inside larger native knob bounds. Override those bounds for progress only so adjacent clicks seek; retain native volume geometry and tracking. Native click regression reproduced before the fix and passes afterward.
