SDL: [Wayland] Cursor keys and return key with phosh+squeekboard (on-screen keyboard) not working

Cursor keys and the return key under SDL_VIDEODRIVER=wayland with phosh+squeekboard (on-screen keyboard) are sadly not working when pressed on the squerkboard keyboard. With SDL_VIDEODRIVER=x11 they work, letters and backspace also work just fine.

Versions:

• Phosh: 0.17.0
• squeekboard: 1.17.1
• SDL2: 2.0.22
