/**
 * Test expanding a pip window by double clicking it
 *
 * To run this test: `atest WMShellFlickerTests:ExpandPipOnDoubleClickTest`
 *
 * Actions:
 *     Launch an app in pip mode [pipApp],
 *     Expand [pipApp] app to its maximum pip size by double clicking on it
 *
 * Notes:
 *     1. Some default assertions (e.g., nav bar, status bar and screen covered)
 *        are inherited [PipTransition]
 *     2. Part of the test setup occurs automatically via
 *        [com.android.server.wm.flicker.TransitionRunnerWithRules],
 *        including configuring navigation mode, initial orientation and ensuring no
 *        apps are running before setup
