I was going to try out the new "playerssleepingpercentage" gamerule. I was feeling lazy to type out the wholr name so i was going to use the autofill option. Thats when I discovered something. The D-Pad left and right would not put the autofill option into the chatbox.
Steps to Reproduce:
1. Go to any world (doesn't have to be yours) that you can use command on.
2. Type any command that supports autofill in chat
3. Type out part of an input fpr the command.
4. Press either D-Pad left or right
Observed Result:
The autofill options do not enter the chatbox
Expected Result:
The autpfill options should enter the chatbox.
