I think this behaviour is all right. There is a punycode form for IDN domains, 
and 
filter_var undestands it well enough, yet not without some issues. But I think 
punycode is way to go.

And by the way, "тест@тест.рф" is invalid email anyway, because 
mailbox can't 
contain IDN characters, I think it violates some basic SMTP RFC. Valid domain 
would be like "test@тест.рф".
