Martin Gräßlin d651d18791 Correctly manage windows on all desktops when using present windows in desktop grid.
That is remove the window from all desktops on drag begin and attach the window to the mouse cursor. On release add them back to all desktop.
That way it's possible to move pinned windows to other screens and it fixes a crash.
BUG: 220582
