Answer 1

The manual says aboult .focus() call

This method is a shortcut for .trigger('focus')

and from the .trigger() topic

Although .trigger() simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.

So as I understand it, the call $(this).focus(); is supposed to trigger the OnFocus event (if there is one attached to the object) but is not quaranteed to actually set/change the focused object.
