Bug occurs when USING IME.

[marszhou]

Thank you for your great job. I'm glad that Slate is a lot easier of using than Draft-Js.

I found this bug when I use Chinese IME on MacOSX (I consider that other language which is input by IME will also cause the same problem, not verified).

You can duplicate it by doing this:

ex:

• Add 3 blocks, and every block contain some letters.
• Then select multilines.
• Then type a letter when Chinese IME is active.
• Then press spacebar or return key, exception comes out.

Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

I've seen the same issue on Chrome 68 - I don't think this is exclusive to IME in any way:

I think this is fixed by PR #2218

Closing in favor of #2368, if you think this is unrelated let me know and we can reconsider.
