bug

What is the current behavior?
Using Windows 10's swipe keyboardin Edge can corrupt editorstate. Console log display: "Unable to get property 'replaceChild' of undefined or null reference'.
Note:
This only happens if you use the swipe feature at the beginning of a new line.

*If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. *
Can be reproduced on draftjs.org or https://jsfiddle.net/stopachka/m6z0xn4r/.
Steps:

• Enable Windows 10 Touch Keyboard. This requires a windows device with keyboard detached (tablet mode). It's possible to simulate this environment with VMWare on Mac if you tweak the config to simulate touch support, and force enable tablet mode in settings.
• Use Edge to open draftjs.org, swipe hello on the Touch keyboard.
• Observe error in console. At this moment editorstate can be in a bad state. (can't type / delete / error in console).
