DockSite.CanToolWindowsDock property for LinkDockSite

Hello,

I'd like to use LinkDockSite as the following.

- DockSite1 : DockSite.CanToolWindowsDock = True

- DockSite2 : DockSite.CanToolWindowsDock = False

Would you please advice how to do it?

My source code is below.

ToolWindow1 can be docked to DockSite2.
