Ah. I removed webkitPreservesPitched entirely from Blink because it
wasn't implemented on any platforms, maybe you could do the same on

More importantly, is it possible to support this on iOS, and is it
likely to bubble to the top of your priorities any time soon if it
were added to the spec? I don't think it's high priority for anyone
working on Chromium, but unless Safari and Firefox are ready to drop
their prefixed APIs entirely it still seems like a good idea to get
what little interop we can by standardizing.
