Research direction

Start by inspecting RecyclerAdapter.onBindViewHolder at RecyclerAdapter.java:765 and trace the LayoutElementParcelable used during the reported Chrome-to-Amaze rename flow. Reproduce the resume scenario on Android 10 if possible, then verify that returning to the file list no longer crashes when the layout element is null.
