Modal MessageDialogs are shown in all workspaces
Xorg, GNOME 3.32.x, Solus 4
It seems like MessageDialogs thrown by some window, for example Nautilus when a copy operation fails, are shown in all workspaces in the same position of the dialog in the workspace with the window that initially triggered it, while the parent window is clearly shown only in the "right" workspace. Not sure if this affects all modals or just this particular case. Please notice that I am still (sigh) on Nautilus 3.26 due to distro packagers, so the correct implementation might have changed since.
