    a11y-settings: Enable toolkit-accessibility when using the magnifier
    
    The gnome-shell magnifier uses AT-SPI caret and focus events to follow
    keyboard navigation. While GTK emits those as long as it can connect to
    the a11y bus, other toolkits/applications such as Qt or Firefox check
    for the IsEnabled property which follows this GSettings key.
