Bug on hyperlink focus function

[Paulaner]

Working with hyperlinks and hyperlink focus functions I experienced a buggy behaviour: let's suppose we have two very close hyperlinks (i.e. one directly above the other on two different lines); when I move the mouse over link1, the focus function is correctly triggering a "gain focus" event. But when I leave link1 and move the mouse over link2, the focus function fires a "lose focus" event for link1 but doesn't fire a "gain focus" for link2. And if I move between link1 and link2, no more gain focus events are triggered.
