Reviewed by Yusuke Suzuki.
There are multiple paths which would allow us to put an element into
m_forwardReferencesInLookbehind; the previous condition checking for
forward references with a zero-repeat quantifier would sometimes get
out of sync with the elements being added, meaning that we would end
up with an incorrect vector state.
