window: Prevent resize cursors from sticking

Browse Source 
When a modal dialog is smaller than its parent,
we were keeping the resize cursor from the dialogs
edge all over the parent window, which looks
really irritating, since the resize cursors are
closely associated with the window edge. Fix
this by falling back to the default cursor
outside the grab widgets surface.
