@interface InterruptibleChromeCoordinator : ChromeCoordinator

// Interrupt the coordinator to immediately tear down the views it manages.
// Dependending on `action`, the interruption may be done asynchronously
// with/without an animation, or without dismissing the views when the
// interruption is for shutdown (e.g., tearing down the scene). `completion` is
// called when the interruption is done. Simply calls `completion` if the
// method is not overridden.
