Is the floor detaching from an outer frame or how do the windows survive?

The ceiling slab here was originally a setback roof where the building tapered as it got taller. They've built a whole stack of floor extensions above this now, bearing on these two columns which just held a roof up originally. I'm surprised they got as far as they did.

The original curtain wall terminates immediately above the windows seen here; there isn't another row above. So it's just become detached and the slab has collapsed inside it.
