When expanding a submenu, we currently use a single tween to animate both the submenu actor and the source arrow. We do this by tweening a monkey-patched JS property on the main actor, which we then use to update the arrow's GObject property on updates. As Clutter cannot animate random JS properties, this trick will prevent us from using implicit animations here. The only reason I can think of for using a single tween is to keep both animations in perfect lock step, but as expansion and rotation are visually quite distinct, this shouldn't be required, so just set up separate animations for each actor. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
