Short description of error
When I select a Window object (which is duplicated linked [alt+d]) which has array modifiers and change to Edit Mode another linked window (alt+d'ed object) shows current selected modifier on all of them.
Exact steps for others to reproduce the error
Open Blender with default layout and add an object then duplicate it (using alt+d). On two objects give them different Array modifiers and then toggle between them in edit mode.
In attached file just toggle between Cube and Cube.001 and go into Edit Mode on first and on second separately.
