[BUG] Supressed ETB abilities are not trigged from Blink/Flicker effects

[Zncon]

When a card with an ETB such at Cloudblazer or Wall of Omens is enchanted with an ability suppression effect from Lignify, Frogify, or Darksteel Mutation, blinking/flickering the creatures causes the enchantment to correctly drop off, but the ETB does not trigger.

Rule 400.7 should mean the creature reenters as a new instance with no connection to it's previously enchanted state.

Yeah, this fails for ExileThenReturnTargetEffect (e.g. Cloudshift) although it does pass for ExileReturnBattlefieldNextEndStepTargetEffect (e.g. Turn to Mist).

The effects from BecomesCreatureAttachedEffect that remove abilities and change subtypes don't appear to get cleaned up in time.

I thought game.getState.processAction(game) would account for that. Needs more research.
