We don't explicitly support this but it happens to work in Stack. We'll give it the same semantics as replaceState.
...without dropping the update. This won't work the other way around, if you assign to this.state before calling setState. we'll add a deprecation warning so people stop relying on this pattern.
We'll remove support for this in a future release, though we'll likely still warn.
Tightens up the test a bit to prevent regressions.

We don't explicitly support this pattern, but it happens to work (kinda) in Stack. We'll give it
replaceStatesemantics and print a warning so that people stop relying on this pattern. In the future we'll remove thereplaceStatebehavior but keep the warning.
