Link to updated example:
https://raw.githack.com/w3c/aria-practices/issue986-toolbar-button-tooltips/examples/toolbar/toolbar.html

Changes:

  1.  Changed references from "tooltip" to "popup label"
  2.  Added global ESC key feature to close any popup label, even when focus is outside the toolbar.  NOTE: Feature is not a lot of code either, so in this case fairly easy to implement.
