There are two separate systems trying to manage touch events on the `MDCButton`. First, the button itself uses its standard `UIControl` event infrastructure to trigger ink ripples. Second, an external `MDCInkTouchController` attaches its own gesture recognizers to do the same thing. This creates a conflict where both systems respond to the same touch, causing two ink animations to be created and displayed simultaneously, which results in incorrect visual feedback.
