Found the reason why dash quality did not work on yewtu.be.
It was absence of "Kaspersky Protection" addon in browser. After installing it yewtu.be started to play dash. This is the first time I encountered a website that required this addon to be installed in order to work, and I remember that yewtu.be worked fine without this addon in january.

Also can be fixed by unticking "Inject script into web traffic to interact with web pages" in Kaspersky's Security settings → Network settings.
