Purple Belt's Gi Pants Fall During Stack Pass Attempt

Two purple belts battle at an IBJJF tournament. The competitor in the white gi drives forward with a heavy stacking pass attempt. She has her opponent in the blue gi folded up, hips elevated high off the yellow mat. The pressure is intense. But something's wrong with her uniform. Her white gi pants have slipped down during the exchange, exposing her black compression spats underneath.

The referee spots the malfunction immediately and steps in. He raises his hand to halt the action. The blue gi competitor releases her frames and sits back on the mat, catching her breath. The white gi grappler realizes what happened. She stands up and starts pulling her pants back into position while the ref gestures at her waist.

The match pauses completely. The blue gi competitor adjusts her sleeves and waits patiently. Her opponent turns slightly away to retie her drawstring and secure the gi pants properly. The referee crouches nearby, watching closely to ensure IBJJF uniform standards are met. The stacking position was working. The pass attempt had real momentum.

Will the white gi competitor maintain that pressure advantage when they restart? Can the blue gi grappler use this break to recompose her guard?
