This is a result of the way .trigger() works; #3827 has the same cause. Focus in particular is problematic because the native DOM .focus() method does not call any handlers if the element is already focused, but there is jQuery code that expects focus handlers to *always* be called as they are today. So we can't just call the native method and be done with it.

Since I have #3827 already I'll take this one as well, but I'm not sure we can make it better. Perhaps differently quirked, but not necessarily better and certainly more complex. For example we can insert a sentinel event handler on the focus event, run the DOM focus method, and see if it fires; if not we would manually trigger any focus/focusin events.

Fix #12868. Use native focus/blur to get event order right.

Now focus and focusin listeners are executed in an inconsistent order when trigger('focus').

If element does not has focus, then focusin listeners are executed first (which is right by calling native focus).

Else if element is focused, then focus listners are executed first and focusin listeners are executed second by bubbling. (which is wrong by bubbling, i think).

Maybe you should execute focusin listeners first in trigger() as a special case (which needs a lot of code change and perfect for focus event) or simple make focus event noBubble.
