/**
 * Test Pip movement with Launcher shelf height change (increase).
 *
 * To run this test: `atest WMShellFlickerTestsPip:MovePipDownOnShelfHeightChange`
 *
 * Actions:
 * ```
 *     Launch [pipApp] in pip mode
 *     Press home
 *     Launch [testApp]
 *     Check if pip window moves down (visually)
 * ```
 *
 * 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
 *        [android.tools.flicker.legacy.runner.TransitionRunner],
 *        including configuring navigation mode, initial orientation and ensuring no
 *        apps are running before setup
 * ```
