That's the exactly intended behavior in the current spec.
The timing of distribution is not observable. That enables UA to optimize
the distribution calc. We can delay the calculation of the distribution as
possible as we can. We don't need to calc distribution every time when a
mutation occurs.

If you find any interop issue in the current spec about distribution,
please file a bug with a concrete example.
