New window created from fullscreen doesn't get focus

Steps to reproduce

1. Run MacVim fullscreen
2. Hit cmd-N to create a new window (this is created as a fullscreen 'space')
3. Type something
4. Notice that what was typed ended up on the first fullscreen window (now not visible), not the new one that should have focus

Expected behaviour

The newly created window (fullscreen) should get focus.

Tái hiện sự cố với MacVim.app trên macOS 12.3.1 bằng cách vào chế độ toàn màn hình và sử dụng cmd-N, sau đó kiểm tra luồng tạo và lấy tiêu điểm của cửa sổ toàn màn hình. Công việc hoàn tất khi thao tác nhập sau khi tạo một cửa sổ toàn màn hình mới được chuyển đến cửa sổ mới đó thay vì cửa sổ toàn màn hình bị ẩn đầu tiên.
