Mouse don't work on ps4 on stable versions/previews since the straw bed addition.

Mouse input does’t work since the bug fixes preview’s of the straw bed and cushions.

Enter the game on ps4, try using a mouse.

It should get rid of the menu “controller disconnected” and the custom mouse of bedrock should appear and work properly.

It don’t recognize the input and keep’s the “controller disconnected” screen. And also only the keyboard work’s.
