Delay when draging & dropping to queue tabs

Currently, queue tabs get switched immediately when moving the mouse over the tabs during a drag & drop operation. This is quite disturbing when you just "accidently" cross the tabs with the mouse. I would like to suggest to implement a delay before switching queue tabs, similar to the delay when draging & dropping files to window entries in the task bar (which will bring the window to front after a short moment).

Thanks, works nicely!
