`MessageDialogContent.messageBox` is not really needed and was only needed to show icons, which is now no longer supported. The styling can also be done using other CSS classes and this makes it a bit more straightforward to add actors to the MessageDialogContent. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/886
GNOME Shell Sass
GNOME Shell Sass is a project intended to allow the sharing of the theme sources in sass between gnome-shell and other projects like gnome-shell-extensions.
Any changes should be done in the GNOME Shell subtree and not the stand-alone gnome-shell-sass repository. They will then be synchronized periodically before releases.
