We block state updates while the indicator for the active workspace is animating. To track that, we check whether the scroll-adjustment's value matches the active workspace index. That works as long as the adjustment's value changes after the active workspace, but not when switching workspaces via SwipeTracker which only changes the active workspace after transitioning to the new scroll value. To fix that, update the indicator on workspace changes as well. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1716>
