Rule not implemented

[mtRoom]

Just writing this here because I couldn't see a contact page on the website.
The es-lint rule "object-curly-newline" doesn't seem to be working, i.e. Any inserted or existing braces remain on a single line whether the option is ticked or not.

It only inserts new lines if "brace-style" is ticked, although I would have thought that shouldn't be necessary, especially given it requires the style to be the same.
