title: How does Google Inbox show a snackbar covering the keyboard?

  <p>How does Google Inbox show the snackbar over (covering, layering) the keyboard? This is not the default behaviour, which I've tested with a basic coordinator layout, the keyboard open and a snackbar: the default behaviour is showing the snackbar <strong>behind</strong> the keyboard. There are many answers on SO to the question: <em>'How do I show the snackbar <strong>above</strong> the keyboard'</em>, but I haven't found how to reproduce Google's own Inbox app's snackbar behaviour.</p>
  
  <p>Can you show me how to achieve this?</p>
