    Chromium: Check for "keyshortcuts" attribute also for browser UI
    
    Chromium is exposing shortcuts for browser UI via the ARIA "keyshortcuts"
    attribute. And other user agents might start taking that approach. So
    check there first; fall back on the Action interface should no shortcuts
    be found.
