UIElement:first_focusable
Advanced
Returns the first focusable element inside this one (or itself). Only elements which can receive input are considered.
It is unlikely you need to override this method when implementing custom elements, but you may have to call it to implement next_focusable.
This method does incur a tree traversal.
