Prop types report missing prop since v3.0.0

[dan-lee]

Since the latest version I get the misleading warning from PropTypes despite the prop is being provided:

Warning: Failed prop type: The prop xxx is marked as required in Foo, but its value is undefined.

Compare the same code with different versions in CodeSandbox and check the console:

• v2.5.5: https://codesandbox.io/s/1rn5qj507l
• v3.0.0: https://codesandbox.io/s/olknzl6wlz

Locally I tried to revert this line:

hoist-non-react-statics/src/index.js

Line 41 in 69090b6

const objectPrototype = Object.prototype;

Back to this:

hoist-non-react-statics/src/index.js

Line 32 in 03a7f2f

var objectPrototype = getPrototypeOf && getPrototypeOf(Object);

And it seemed to work again. I am not sure what's happening there and I did not investegate further, just wanted to share some insights.

Ah, I see what's happening here. It has to do with how we detect the type of components here: https://github.com/mridgway/hoist-non-react-statics/blob/master/src/index.js#L60. I will follow up on this with a fix.

This should be fixed in v3.0.1.

Thanks for the quick resolution
