   This bug is pretty easy to reproduce in all 5.x versions. Let's take this example:http://ift.tt/15nENay
   

   Steps to reproduce:
   
   - Collapse all groups except for the first one.
   
   - Select the first record of the first group.
   
   - Press Alt+End to jump to the last record of the last group.
   
   - Press PageDown and the selection will jump 4 records up.

   
   

   Didn't test with the other selection models.
