The upstream bug seems to have been fixed already in 5.5.27 release.
From http://dev.mysql.com/doc/refman/5.5/en/news-5-5-27.html
" If an account had a nonzero MAX_USER_CONNECTIONS value, that value was not always respected. (Bug #65104, Bug #14003080)"
So, it will be in upcoming PS 5.5.27 release as well.
