[Webkit-unassigned] [Bug 187971] Move-constructing NeverDestroyed should move construct underlying object instead of copy constructing it

--- Comment #1 from Daniel Bates <dbates at webkit.org> ---
The issue is that the NeverDestroyed move constructor is moving the passed NeverDestroyed object instead of the underlying storage when placement-newing T. As a result, the compiler implicitly converts the to-be-moved-from NeverDestroyed to const T& and invokes T's copy constructor.
