There are some linting issues and the style const doesn't have a nonce property

Conflicting issues here. addHeadObjs is deprecated in favor of push but when I use it push does not exist. (so had to revert back) Then type HeadAttrs ends up not existing so decide to remove it, and now nonce does not exist. Going to need some pointers here.
