As part of removing SkinMinervaBeta, we should feature flag the font-changer code.
- Visit https://en.m.wikipedia.beta.wmflabs.org/wiki/Main_Page and go to the settings by tapping on the hamburger menu -> settings.
- Make sure you don't see an option to increase the font size, something like this:
- Opt into the beta mode and go back to the settings page.
- Verify that you see an option to change the font size.
- Increase (or decrease) the font size and go to some page (e.g. Main page) and verify that the site font size has indeed changed.
