LGTM.  You and I are going to be fighting over RUntimeEnabledFeatures today. :)

setSpeechSynthesisEnabled(bool isEnabled) { isSpeechSynthesisEnabled =
isEnabled; }
I suspect I just broke thsi part of the diff.  These are now autogenerated as of

Interesting.  I didn't know this worked as a class-level attribute for
suplements.  Cool!
