<pre>Consider the case where
propagate on container copy assignment = true
propagate on container move assignment = false
and focus on move assignment.
Suppose that the (stateful) instances of the allocators are not equal to one
another.
In this case, __move_assign delegates to assign. As far as I can tell, this
delegates to copy assignment. However, the latter considers propagation on
container copy and not container move.
This gives the wrong outcome in the case described.</pre>
