i'm trying to glue these adjacent AI via right click menu, but right clicking a selection of multiple AI deselects all but the right clicked object. compare the behavior to the same actions performed on midi items, above
EB: right clicking doesn't deselect all other selected AI
EDIT: the issue is that 1 pixel movement you can see my mouse cursor making before right clicking.
the act of pushing a mousebutton often causes a small mouse movement. the same inertia/correction that has been added elsewhere needs to be added here too
