Able to reproduce the issue on MAC 10.11.6, Windows 10 and Ubuntu 14.04 using chrome reported version #54.0.2840.99 and latest canary #57.0.2934.0.

This is a non regression issue as it is observed from M30 old builds.

Hence, marking it as untriaged to get more inputs from dev team.

Thanks,

Did you create the test PDF? If so, can we add it to our test repository?

Yes I created it with PDFKit. You can do whatever you want with it.

Thank you. We'll try to look at this sooner rather than later.
