Confirmed, the settings correctly change com.canonical.Unity.Interface text-scale-factor from 1.0 to 1.25 but Unity fails to update the gtk setting (which it's supposed to do), reassigning there

This used to work in GTK+ as well, but stopped working with this commit: https://git.gnome.org/browse/gtk+/commit/?id=e643ddfd168f81d80400cf67a0ff4b8808ea043c.
