isDragReject should be true if the DragEvent contains more than the max number of files

Do you want to request a feature or report a bug?

• I found a bug
• I want to propose a feature

What is the current behavior?
When setting the maxFiles prop, if I drag more than that number of files over the dropzone, isDragAccept is true, and isDragReject is false.

If the current behavior is a bug, please provide the steps to reproduce.

1. Example: https://codesandbox.io/s/stoic-wilbur-3elnq?file=/src/app.js
2. Try dragging more than 1 file over the dropzone

What is the expected behavior?
isDragReject should be true, i.e. the border should be red in the example

If this is a feature request, what is motivation or use case for changing the behavior?

Please mention other relevant information such as the browser version, Operating System and react-dropzone version.
Tested in chrome. Latest version of react-dropzone (11.2.0)

I think this should be fixed now (see #1020). Gonna close it. If there're still issues with this, please let us know.
