Global

This setting is global: its value always applies to all your pages. In other words, it doesn't support config inheritance.

You cannot set it at pages/some-page/+config.js: you have to set it at pages/+config.js (or some other global location) instead.

If you want to set different values for different pages, then consider creating a custom setting as shown at Guides > <head> tags > Custom settings.
