Hi guys, first of all, yes, it was a patch that landed early last week and got
reverted due to an assertion triggering. I've fixed that and re-uploaded the
patch, but it seems now something else has popped up :(

I believe I know the root of this new issue - the CSSPropertyTextDecorationLine
is now removed from the vector in
RuntimeCSSEnabled::filterEnabledCSSPropertiesIntoVector(), thus making
Vector::find() return notFound, which causes the crash in line 107 of
EditingStyle.cpp.

I apologize for this - the issue is very quick to fix but got undetected because
I was biased in not running tests *with the runtime feature disabled* after I
fixed this patch the first time. I'll update the issue tomorrow with the proper
fix and tested in various combinations - release/debug mode x runtime feature
enabled/disabled.
