Problem with nested inline tags in Content Editor in Chrome

I have a topic that contains a conref. The conreffed content is a ph tag with a nested i tag. This is a valid construct in DITA, but when I attempt to open the topic in Content Editor, I get an error that the i tag is not expected. This error only happens in Chrome. I have no problem opening the topic in IE 11. 

Has anyone seen this issue before?
