Wrong calculation in seekPercentage() in examples.

[RuZniki]

$event.target.offsetWidth have different value depends on click place.

If we click on the area which not was played before everything {green arrow} seekPercentage works good. Because target area is
$event.target = (div.progress) which have static width.

But if click target in played area {red arrow}.
$event.target = (div.progress-bar) which have fluid width, calculation become wrong.

To reproduce bug, just click two times in one place at red arrow (div.progress-bar).
