<!-- FYI: This layout has an extra top level container view that was previously used
     to allow for the insertion of debug info. The debug info is now gone, but the
     container remains because there is a high likelihood of UI regression relating
     to focus and selection states, some of which are specific to keyboard
     when touch mode is not enable. So, if you, heroic engineer of the future,
     decide to rip these out, please be sure to check out focus and keyboards. -->
