I created a shelf with my Favorite applications. When I open an app from the shelf, it doesn't close immediately after launch, but rather waits till the app is open.
This is an unexpected and inconsistent behavior compared to other app launchers (kickoff, lancelot, etc.)

Reproducible: Always

Steps to Reproduce:
1. Create shelf with favorite applications
2. Open shelf and launch one application
Actual Results:  
Shelf remains open until app opens, so you can launch the same application multiple times (which you might do, in case you didn't recognise it is already launching).

Expected Results:  
Shelf should immediately close after click on app.

If needed I can upload an screencast.
