Demo of inconsistent item focusing

Overview:

 When krunner opens and lists the results after the search input,
 focusing of the item in the results is inconsistent.

Reproducible:
 always

expected:
 What I'd expect is that first item always is and stays focused, so I
 can use arrow keys to navigate to the desired item.

actual:
 - sometimes first item is focused and stays focused

 - sometimes first item is focused, then results from other
   components come in (like scripts/files etc) and focus is 
   set randomly to some other item (most of the time to the
   latest item in the list)

 - if mouse cursor happens to be positioned in area occupied 
   by krunner's list, focused item becomes the item under the cursor

  -- and then the same happens when other results come in delayed; 
     focus can either stay on item under the cursor or switch to 
     the first item in the list

How to reproduce:
 Open krunner, type a few letters which will yield the results
 and watch which item will become focused. Then cancel the krunner
 and repeat the open+search again. Do this a few times to see
 the differences

 Also try moving mouse cursor on the part of the screen where krunner
 list will appear and repeat the previously described steps
