Behaviour as if another keyboard layout was active

I have two keyboard layouts in my “quick list” or whatever you want to call it. Classical German QWERTZ and the NEO 2 layout. However, Minecraft in non-chat-mode ignores which layout I currently have selected and behaves as if I had selected the first one. When I change the ordering of the layouts in the list, the behaviour of Minecraft changes, otherwise it doesn't. Of course, it should be just the other way 'round.
