Held items are not fully displayed to the player in resolutions that are not widescreen

When playing the game in a non-widescreen resolution, items held in the player's hand will not be fully displayed.

Steps to Reproduce:

1. Set resolution to 640x480 (Or any other non-widescreen resolution)
2. Give the player a filled map

   /give @p filled_map 1

3. Put the map in the off-hand

Observed & Expected:

The map will be cut off, not entirely visible.
The map would be entirely visibile just as in other widescreen resolutions

Notes:

This applies to all items, maps are one of the worse offenders though considering it's crutial the player be able to see the entire thing.
