Docking restriction for the toolwindows that are in Floated state.

Hi,

I am able to dock the toolwindows that are in the same docksite but if i float these toolwindows from the docksite which means these toolwindows are in floated state then any of the floated toolwindow Should Not be docked in the other floted toolwindow.

ForExample : i have two toolwindows named toolwindow1 and toolwindow2 in docksite named docksite1,so i can drag the toolwindow1 and dock in the toolwidnow2 but if i float the toolwindow1 and toolwindow2 both then i drag the toolwidnow  then It Should Not dock in the Floated toolwindow2.
