@srenault thanks for the PR. the issue is that this file is actually auto generated from the IE definition files. this makes it easy for us to get an almost accurate DOM definitions without having to update them manually. We plan on updating how the dom typings are generated but for now, we can not make hand edits to this file. If you can log a separate issue, i can get it fixed in our script and update the file.

Ok, I suspected this. It there anyway in my project to override / add a definition of Event constructor without edit lib.d.ts ?

I can not think of one. @RyanCavanaugh ideas?
