With the introduction of the patch 3628a8c4ea2485ee7ee5a81cfd4e0f0fe62b10d6,
it is possible to highlight focused Elm_List and Elm_Genlistenlist items.
However, this feature does not work correctly if one wants to create a custom
highlight theme for Elm_List items.
The whole problem was happening, because the function
_elm_widget_item_highlight_in_theme() was being called in a incorrect
location. This function must be called at _items_fix(), because
there the Elm_List already set the item theme and then it's possible
to check if the one wants a custom highlight or not.
