Rule proposal: Error when adding a class that begins with a dotclassList.add('.
Description
Sometimes, we incorrectly try to add a class that begins with a dot, but linters and indeed browsers do not indicate that this is an error.
The error occurs because we use a dot in selectors for classname, but the dot is not part of the actual class name.
Fail
node.classList.add('.table-of-contents');Pass
node.classList.add('table-of-contents')Additional Info
