Bug when using KeyTable with AutoFill: handle doesn't disappear when scrolling/sorting

Hi,

https://datatables.net/extensions/autofill/examples/initialisation/keyTable.html

When I selected a cell with the mouse and then either 1) scroll with page up/down or 2) change the table sorting, the AutoFill handle still stays in place where it was.

BTW, is there a bug tracker to report such things?

Thanks
Sebastian
