bug
**What is the current behavior?**
example: https://codesandbox.io/s/04393o3k6w
If the `LogProps` is child of `M.Provider`, and `M.Consumer` is used in its children.
When the `M.Provider` is updating, even if the `LogProps` is wrapped in a component that  never updates, it can still be triggered by the callback of `React.forwardRef`, and updates the `LogProps`.

**What is the expected behavior?**
the `LogProps` shouldn't update when the root component had updated, whether or not  `M.Consumer` is used in its children;

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

it's used react@16.3
