Created attachment 195269 [details]
after the following, broken, style declaration,
the next valid style declaration does not get applied
see attached reduction case.
Apparently the changes in CSSGrammar.y.in (r146588) causes this regression.
see also bug 113142
bugzilla can't find firstname.lastname@example.org (author) so assigned it to the reviewer of r146588.
