WebViewClient: Why is onPageFinished not being called on a specific site?

Question

Android

Good afternoon!
I am using WebView with WebViewClient.
I'm testing on two video sites. When loading the first one:
www.metacafe.com/watch/11319719/epic_meal_time_sna...
the onPageFinished method is called, everything is ok.
When trying to load this page:
gidonlinekino.com/2014/09/ruka-na-million
onPageFinished is not called, you can wait indefinitely (onLoadResource loads several resources and that's it...).
Why is this happening and how to catch the end of loading that page?
