I think I fixed this in http://trac.webkit.org/changeset/211382 . Can you try using a WebKit Nightly build from https://webkit.org/nightly/ ? Thanks!

The error still persists even with nightly build. Please check. Please fix this in Coretext also, so this issue is resolved system wide for mac OS and iOS.
