Cancel and ESC key doesn't work on Ore UI Disconnect screen

When you attempt to close Disconnect screen with Cancel key, nothing will happens, and if you attempt to close it with ESC key, it will highlight one of the button.

Step to reproduce:

1. Open Minecraft Preview

2. Join any Featured Server, since you’re on Preview it will disconnect you right away

3. When Disconnect screen appear, try clicking your Cancel key or ESC key

Expected results:
The screen will close and sends you back to Play screen.

Observed results:
Nothing happens if you use Cancel key, or it will highlight one of the button if you use ESC key.
