* [x] I have searched the issue tracker for an issue that matches the one I want to file, without success.

### Issue Details

* **Electron Version:**
  * all (according to docs), tested in 2.0.18 & 4.1.3
* **Operating System:**
  *  Windows

### Expected Behavior
To be able to set the working directory for applications started from the windows jump list

### Actual Behavior
It defaults to c:\windows\system32

### To Reproduce
Not really anything to do to reproduce, just look at the documentation, the parameter isn't there:
https://electronjs.org/docs/api/structures/task
https://electronjs.org/docs/api/structures/jump-list-item

### Additional Information
I'm not entirely sure you will agree that this is a bug but afaict the api seems to replicate what the underlying windows api provides so I assume it's an oversight that this parameter in particular is missing - especially considering how problematic it can be for applications to have c:\windows\system32 as their cwd.
