Steps to reproduce the problem:
1. Run the code below in on any site with text.
2. Copy some text.
3. Look at the console.

What is the expected behavior?
clipboardData.getData('text') should return text

What went wrong?
clipboardData.getData('text') returns nothing

Did this work before? N/A 

Does this work in other browsers? N/A

Chrome version: 56.0.2924.87  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 24.0 r0

Test code, run it on any site with text:
document.addEventListener('copy', function (e) {
        console.log(e.clipboardData.getData('string'));
        console.log(e.clipboardData.getData('text'));
        console.log(e.clipboardData.getData('text/plain'));

        console.log(e.clipboardData.getData('text/html'));
        console.log(e.clipboardData.getData('url'));
        console.log(e.clipboardData.getData('text/uri-list'));
        var items = e.clipboardData.items;
        if (items) {
            for (var i = 0; i < items.length; i++) {
                console.log(items[i].type, items[i]);
            }
        }
});

I want to format the selected text on a site that isn't copy-text-friendly, I've had it with manually fixing the text afterwards in my text editor. Disappointingly but expected, nothing works in Chrome.
