constructor property name breaks highlighting

[AndreasMadsen]

The following code highlights wrong.

const root = new Node({ constructor: { name: 'root' } });
const stateMap = new Map();

This appears to be because of the property name constructor, thus it could be related to #425. However I don't think so, because if I use a different keyword like new it highlights fine.

const root = new Node({ new: { name: 'root' } });
const stateMap = new Map();

Closing as a duplicate of #334.
