A property made non-writable, non-configurable must not be reported as writable
("$1" property of the RegExp built-in)
info: |
[[GetOwnProperty]] (P)
[...]
- If the [[Writable]] attribute may change from false to true,
then the [[Configurable]] attribute must be true..
[...]
(This invariant was violated for the specific property under test by at least
one implementation as of January 2017.)
