Needs to select() inputs that receive focus

[davidtheclark]

Because the plugin is using event.preventDefault() to control focus, it is preventing the default behavior of selecting an input when that input receives focus from a tab.

This is easily restored by changing the tryFocus function to:

function tryFocus(node) {
  if (!node || !node.focus) return;
  node.focus();
  if (node.tagName.toLowerCase() === 'input') node.select();
}
