Does not work in files containing an ECMAScript decorator

[DallasHoff]

Describe the bug

I have found that when a JavaScript or TypeScript file contains a decorator, this extension's features stop working in that file.

Minimal Reproduction

Double click the = for the x and notice the assignment is not selected. Now remove or comment out the first line and notice that double clicking the = now works as expected.

@SomeDecorator()
class SomeDecoratedClass {}

let x = 1;

We might need to upgrade our Babel parser. PR welcome :)
