What is the current behavior?

Steps to reproduce:

1. Open either 'color' or 'rich' example in IE or Edge browser.
2. Write some text and use rich styles and/or colors
3. copy and paste the text.

Current behavior:
IE 11.567 - newlines and styles are dropped completely
Edge - only styles that are enabled for the place you paste into are applied, and newlines are preserved. See attached screenshots.

Expected behavior:
Styles and newlines should both be preserved, like in Chrome.
If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. You can use this jsfiddle to get started: https://jsfiddle.net/stopachka/m6z0xn4r/.

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

I'm not sure when this snuck into Draft. I don't think it came up in previous versions but seems to be present both on master and in v0.10.0. I don't think it was present before v0.10.0.

@flarnie is this issue still being targeted for an upcoming release? I noticed it didn't make the cut for v0.10.1 and was hoping to avoid implementing the changes from the various forks mentioned in #986.
