Start menu behaviors toggle was gone

[Antony Chan]

Hi WP communities,
Am I the only one that missing the start menu behavior toggle? I remembered the previous build 10152(if not mistaken, can only remembered the build before 10158) we can choose full screen start menu when in tablet mode and normal start menu in desktop mode.

I can't find this settings anymore, its either always full screen or the other one. Current build 10162.

Thanks.
