Gtk: Drag 'n Drop in JavaFX 2.2 behaves differently depending on the platform. (Windows/Linux)

Hi,

I've found one problem in JavaFX 2.2 with the drag 'n drop. It seems to behave differently depending on which platform you are using. If I for example have implemented a DnD functionality for a ListView, where you can drag one item in the list to re-order it, in Windows this seems to be working fine. But when I try the application in GNU/Linux it seems to be removing the selected (and dragged) item when I hover over some other item in the list.

There is an example on the web that I've tried that have this behaviour, for me at least:

Maybe its just me?
