My IDE (Sublime Text 2) just highlighted Style in the same manner it highlights Object or Math in javascript mode. Is Style used for something in javascript? This only happened for uppercase Style, not style.

A quick test in gist did not result in the same highlighting: https://gist.github.com/3230637
Edit: Added Foo to show it’s not just constructor syntax highlighting.
It isn’t a reserved word, but it is an object in the DOM.

Many IDE’s will highlight this because it is a common object, like
ObjectandMath.
