How to disable *.d.ts suggestions in JavaScript Intellisense?

I recentlty upgraded from ReSharper 8 to 9. I write a lot of JavaScipt (using the Ember.js framework), so one thing that drives me literally ;-) crazy is that everytime I write

this.get(

ReSharper "autocompletes" it to

this.__defineGetter__()

Apparently __defineGetter__ comes from dHTML.d.ts (TypeScript?)

Is there a way to turn this off or to disable TS support in general. I don't need it.

Thanks,
Stefan
