Start with CompressedExplorerFragment and its onDestroyView lifecycle, then trace the listener path from AppBarLayout through FastScroller to the detached FrameLayout shown in the LeakCanary report. Reproduce the decompression and view-destruction flow with LeakCanary; done means the FrameLayout is no longer retained after onDestroyView.
