Copying / cutting / pasting in IE11 does not preserve newlines correctly

Bug

What is the current behavior?

There are two bugs here:

• Copying text from a DraftJS editor appears to duplicate newlines (see what happens when it's pasted into a textarea).
• Then, when you try to paste the selection back into the DraftJS editor, it removes all of the newlines.

It should preserve the newlines exactly as they were copied.

Which versions of Draft.js, and which browser / OS are affected by this issue? Did this work in previous versions of Draft.js?

Latest Draft.js, tested on Windows 7 IE11

I fixed the copy issue manually by checking to see if the browser is IE11, setting up copy / cut event listeners on the document, checking to ensure that some parent node of the copy / cut target was our draft editor, and manually placing the correct plaintext into the clipboard via window.clipboardData.setData('Text', selectedContentState.getPlainText());. If this doesn't sound too dumb, I could create a PR with this approach

Cut, copy, and paste are rather difficult and we found that Draft's support was lacking in several ways. In our fork we have a separate div next to the editor that accepts the paste event and then we steal the data after it has been pasted. The initial implementation (with bugs that later PRs fixed) is https://github.com/textioHQ/draft-js/pull/21/files. We have a third div that we use to support copy operations for IE as well...

@gdehmlow @colinjeanne were you'll able to get your fixes merged back into the main draft-js repo? If not are there any plans to do so?

Unlikely. That would require time that I don't have to invest here and a larger discussion with the Draft team because our changes affect copy/paste pretty significantly. It's not clear if those changes would be something that they'd want more generally.
