Application panel first load with extra padding

At first load when no data is in the browser cache, the Application panel is displayed with extra padding between its entries.

Steps to reproduce:

1. Load any page with the Application panel displayed and the cache emptied -> extra padding
   
2. Refresh the same page without clearing the cache (F5) or click to an internal link to a page with the same panel displayed -> regular padding is back
   

It could be related to the fact that this panel is asynced and cached.
