First let me say great library and I'm enjoying/heavily-using it on a showcase site for some open source packages I'm working on. So, thank you.
Issue is applying css style to a string with multiple periods/dots does not style correctly.
For example, console.log('%cnested.dot.path', 'color: green;'); will only color .path portion of the string as green whereas if you look at the log entry in browser console the entire string correctly styles as green.
