I reviewed some of the Timuu forks and one of them was working better. It seems that the problem is the theme does not reference the most up-to-date version of Persona theme. When I put persona.js file into the /lib folder the problem was solved.
So, if anyone wants to use the theme:
- Make a fork
- Copy up-to-date version of persona.js and autohiding.js files into the /lib folder of the theme
