This works for me in Safari 10.0.3 on macOS 10.12.3, both in Bugzilla and on this website.

What version are you using?

As I said, this does not reproduce for me.

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!

[P K]

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.

[P K]

FYI. This issue is system mac OS and iOS.
