Why does VKontakte not define micromarkup?

Question

HTML

They asked me to add micro-markup to the site with a Cyrillic domain, so that when sending a link to the social. networks had a beautiful picture, etc.
Implemented several open graph meta tags, tested it on Skype, Facebook and VKontakte. A beautiful link with a picture title and description appeared on Skype and Facebook, but VKontakte flatly does not want to recognize the link as such.
Tried both Cyrillic and ponycode both with http and without it, all to no avail.
Perhaps VKontakte, unlike Western social networks and instant messengers, does not recognize Cyrillic domains as such? Or is there some trick I don't know?
Google didn't answer...

Have you cleared the cache?
Why doesn't VKontakte pick up my OpenGraph image?
