[confirmed]Morph doesn't honor Humble

Describe the Bug:
If you Humble a face-down morphed card, you can still unmorph it.
Which card behaved improperly?
Humble and all its friends.
Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Dev 2bba4ec.
What exactly should be the correct behavior/interaction?
Stated most clearly in the still-recent Khans of Tarkir release notes: "If a face-down creature loses its abilities, it can't be turned face up because it no longer has morph (or a morph cost)."
Are any other cards possibly affected by this bug?
Superficially? Plenty. Hence the REPORT here creatures not affected by Humility topic. I'm listing it separately because it's unusual for a couple different reasons:

Superficially? Plenty. Hence the REPORT here creatures not affected by Humility topic. I'm listing it separately because it's unusual for a couple different reasons:
- You should still be able to unmorph if the card loses its activated abilities. Morph is solely a static ability, even though it's implemented as an activated one.
- Face-down cards don't actually have any abilities to lose, even if they're face-down cards with morph. They still get affected by Muraganda Petroglyphs, for example.
- The closely-related Manifest mechanic shouldn't be affected by losing either activated or all abilities, as stated in the Fate Reforged release notes. (Mind, that doesn't seem to have any support in the Comprehensive Rules, and it's freakin' inconvenient if you've programmed loss-of-abilities at the engine level instead of trying to re-implement it separately in every single card.)
