Fix glitches with custom list title viewports

Elements were not being drawn correctly or
title text appeared delayed in several places
when using themes with a custom viewport
for list titles.

E.g.:
- after deleting a shortcut
- when returning from a warning screen in
Playlist Viewer
- returning to some Settings screens
- in "Playing time" screen
