Cannot navigate game menus using arrow keys

Issue Description:

Enter and Escape work as they should, delving deeper into and backing out of menus respectively, and Tab/Shift-Tab also function to select menu items, but the arrow keys, which are purported to be able to move through menu items now, do nothing.

 

Steps To Reproduce:

   1: Start Minecraft Java Edition 1.14

   2: Attempt to select menu items with arrow keys.

 

Result:

Menus are not navigable by arrow keys.
