Collectible Card Game Headquarters

Describe the Bug:
While an opponent has Kismet in play, canceling the X payment prompt while casting a card such as Chalice of the Void will cause the card to be returned to your hand - but tapped. (See screen shot)

Apparently this is not just cosmetic, since a tapped card in your hand seems to be un-castable. In fact, the tapped card in your hand acts like it is on the battlefield somehow. For example, Chimeric Mass can be activated while in your hand for 1 mana.

Which card did behave improperly ?
Kismet and canceled spells

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
BNG v2

What exactly should be the correct behavior/interaction ?
Cards in hand cannot be tapped.

Are any other cards possibly affected by this bug ?
At least X costed permanents.

Tested with Chalice of the Void and Chimeric Mass

If there's any X-costed or otherwise cancellable-while-being-cast permanents that come into play without counters, they'll probably keep them too.

Needs put_card_on_stack1() to move into C, which is nontrivial.

Or maybe we should made a check if "cancel != 1" before adding the STATE_TAPPED...
I'll check if that's not too recoding needed for that.
