Research direction
Investigate the pulse animation implementation in the Material framework, specifically how UIView.transition or custom animation views handle touchesCancelled. Check files like PulseView.swift or AnimationController.swift. Review existing comments in issue #1181 for any suggested fixes or workarounds. Determine if the issue is caused by a missing call to super.touchesCancelled or if the animation state needs to be reset in response to cancellation.
