The GS Tooltip takes to long to build.

[Jacobvdb]

Passing the pointer fastly over the text "as this tooltip" causes an error resulting in the tooltip staying visible.
It seems that the time to build the tooltip takes too long (as it goes back to the server) in order for mouseout event bound with the noFocus() function to find the Tooltip and to remove it.
The error in the console "Cannot read property 'parentNode' of null"
Any ideas?
