Adjustments in gradient slider not applying to grouped objects
When adjusting the gradient slider for a group of objects, only some of the objects are affected by the slider. The rest of the objects don't change. Applies to both linear and radial gradients, but problem more frequent for radial.
(In screenshot, the lower-right corner shows how some of the objects follow the gradient slider adjustment, but the rest of the objects in the group don't change. Using macOS High Sierra and Illustrator CC v23.0.1.)
