changing workspaces while dragging confuses gtk

[Shahms King <shahms shahms com>]

I recently hacked up a patch to allow hovering over the workspace
switcher while dragging something to change workspaces and in so doing,
discovered a bug with DnD.  Specifically, after changing workspaces the
DnD code "remembers" the window positions from the workspace on which
the drag was initiated and basically pays absolutely no attention to the
windows on the new workspace.  This means dragging and dropping only
works on "sticky" windows, which is just about useless in this case...

Obviously, at this stage in development it's a low-priority problem, but
I'd like to know where I should start looking to fix it... (And what
component to file it under).
