There is no typo as far as I've checked. The following was added to
#if defined(ENABLE_CSS3_TEXT_DECORATION) && ENABLE_CSS3_TEXT_DECORATION

+1 on that. I've re-checked the build bot output and it seems the
issue is actually caused because CSSPropertyWebkitTextDecorationLine
gets undefined. So I'm starting to believe the fail reason is
something else skipping from my eyes. The actual bug related to this
