Is this the root cause for bug 161254?
*** Bug 161831 has been marked as a duplicate of this bug. ***
The problem is that this no longer works: transition: background-color 1s; transition-delay: 1s; (same for animations). CSSParser::parseTransitionShorthand() also sets prefixed properties, but parsing the longhands does not, so we behave as if -webkit-transition-delay:0 is set. Indeed, changing the second line to -webkit-transition-delay: 1s works around the bug.
