Inline edit error

Hi
Whenever I use inline edit and click save the table is moved down by the number of lines edited.
I have publised an example to my demo account - no login needed to the testerinline project.

1. Select all three line
   
2. Click edit selected
   
3. Click save all
   and you see the table move down by three lines.
   This is OK until you edit 10 or so lines in one go.
   Many thanks for the great support
