Disguised permanents' face-down disguises do not gain Ward 2 when cast from any non-hand zone

[shy creek]

Hi all, this is from testing on the latest May 31st snapshot. I discovered this when I attempted to cast the alchemy card [[Roalesk, Prime Specimen]] face-down with his disguise cost from the command zone. It seems that casting disguised creatures from the command zone, graveyard, exile, or anywhere other than hand does not confer the Ward 2 ability onto the face-down permanent, which all disguised/cloaked creatures should have. Casting them from hand does apply Ward 2 as normal.

Thanks for all your hard work!

Whenever Roalesk, Prime Specimen or another permanent you control is turned face up, you may pay . If you do, if X is 1 or more, conjure a duplicate of a random creature card with mana value X into your hand. Cloak it. It gains ": Turn this creature face up" for as long as it remains face down.
