The Bug:

The correct order for selecting buttons using the TAB key would be from top to bottom and left to right. This is not the case for the buttons in the multiplayer warning menu.

Steps to Reproduce:

• Load up a fresh instance of Minecraft and click the "Multiplayer" button.
• Hit the TAB key several times and observe how buttons are selected.
• Take note as to whether the buttons in the multiplayer warning menu are selected in order when using the TAB key.

Observed Behavior:

The "Proceed" button is selected first, then the "Back" button, and then the "Do not show this screen again" checkbox.

Expected Behavior:

Buttons in the multiplayer warning menu would be selected from top to bottom and left to right. Instead, the "Do not show this screen again" checkbox would be selected first, then the "Proceed" button, and then the "Back" button.
