Their content was not ignored. Original function works correctly.

// correct
dateFormat('2017-06-16', "'yyyy'") // yyyy

// wrong
dateFormat('2017-06-16', '"yyyy"') // "2017"

We just ran into this issue in our project using a custom mask as well, it would be great if this could be accepted as it solves the problem. @felixge

I'm not maintaining this project anymore and have notifications turned off by default. If one of you wants to help in the future, and e.g. cut a npm release for this, please let me know your GH+NPM usernames so I can give you access.
