[core/theme] Improve items that are lists

Browse source 
Until now, using a list as prefix/suffix didn't work as expected,
because the corresponding method for retrieving the value was called
multiple times, and each time, the next icon would be retrieved.

Changed the logic inside the theme to only update the indices every time
that an actual update was happening.
