Copying into a code block doesn't retain code block formatting.

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

Bug.

What is the current behavior?

It is not possible to paste a code snippet into a Draftjs code block. When you try, the text on the clipboard is copied into the editor, but the code block formatting is lost.

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. **

1. From a code editor, copy some code into the clipboard.
2. Go to https://draftjs.org/
3. Click in the editor window.
4. Click on "Code Block" in the toolbar.
5. Try to paste the code on the clipboard into the editor code block.

What is the expected behavior?

The expectation is that the code copied from the text editor would be inserted into a Draftjs code block.

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 using Chrome Version 59.0.3071.115 (Official Build) (64-bit) on MacOS version 10.12.5.

I'm new to Draft.js so I don't know if this was working previously.
