Steps to reproduce the problem:
1. I use this to implement clipboard copy https://www.npmjs.com/package/react-copy-to-clipboard
2. On a Mac, I confirm that such plugin will copy text to clipboard
3. I now run the headless chrome on circle ci, the program perform the same thing (click on the button that is supposed to copy the text). Then I use "xclip -o" to inspect the clipboard

What is the expected behavior?
There should be some text in the output of "xclip -o"

What went wrong?
The output is empty. That mean chrome didn't copy anything to clipboard

Did this work before? No 

Does this work in other browsers? Yes
