import-hidden symbol is still re-exported

In the following, I get different behaviour with ghc-7.0.4 and ghc-7.2.2:

module I ( module Text.ParserCombinators.Parsec ) where
import Text.ParserCombinators.Parsec hiding ( State )

module U where
import I
x = undefined :: State () ()

with ghc-7.0.4, I get the expected

ghc-7.0.4 --make U -package parsec-3.1.2
[2 of 2] Compiling U                ( U.hs, U.o )

U.hs:4:18: Not in scope: type constructor or class `State'

while ghc-7.2.2, it compiles. Is this a feature?
