New Editor main page does not have close game popup

The Ore UI version of the Editor’s main page does not allow to exit the game with the “exit Minecraft” pop-up. In the regular game and the old UI, you could press Esc or the mouse return button to open this pop-up and close the game, see the attachment.

Steps to reproduce:

Launch the Editor and make sure it uses the Ore UI main menu (may require to enter and leave a world first). Press Esc or the assigned Return key.

Expected result:

A pop-up opens in the Ore UI main menu (both projects and servers tabs) which allows to close the game.

Observed result:

Nothing happens.

This means that the game always needs to be closed with the app close button in windowed mode, the taskbar, or goold old Alt+F4. Especially on fullscreen, this is a noticable issue.
