console.lua: don't clip items if OSD dimensions are not initialized

If you open the menu at startup, e.g. with --input-commands, it rarely
clips items completely because OSD dimensions are still 0, or as if they
were 100 because those are the default values before receiving property
notifications. Avoid this.
