Allows keyboard users to scroll the content of the --scrollable dialog:
- Adds a focusable element to the dialog's content
- Adds a 1px outline on focused links within dialog content
- Changes dialog content from Latin ("Lorem Ipsum") to English ("The Wonderful Wizard of Oz")
Makes "OK" button the default action in Confirmation dialog:
- Pressing the Enter key when a list item has focus will now close the dialog
