Yes, both of these conclusions are correct.
OK. What do we do if we discover that throwing from the defineProperty
call with a non-configurable property descriptor is not web-compatible?
I'm going to try doing it in Firefox, and would welcome other UAs
doing it ASAP to figure out whether we're in that situation.
