Uncaught TypeError: Cannot read property 'nodeType' of null at editOnInput

A bug

What is the current behavior?

DraftJs is used to power a timed transcript editor. (@bbc/react-transcript-editor) with blockRendererFn used to have a WrapperBlock to display speaker names and time-codes at paragraph level.

Trying to add a html select element to make it easier to change speaker labels within a WrapperBlock in this PR. bbc/react-transcript-editor#210

However it seems that whenever I make a selection with the select element I get this error in the coneole.

Uncaught TypeError: Cannot read property 'nodeType' of null
    at editOnInput

I am not quiet sure what this means or it might refer to?
I found this helpful issue/comment #1085 but would love to learn more about the inner workings to understand why, if my hypothesis is right, calling select in a WrapperBlock might be triggering this?

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/gmertk/e61z7nfa/.

To reproduce checkout this PR bbc/react-transcript-editor#210

1. git clone repo / branch

git clone -b speaker-dropdown-select-2 git@github.com:pietrop/react-transcript-editor.git

2. cd into folder - cd react-transcript-editor
3. npm install
4. npm start
5. storybook starts on http://localhost:6006
6. click button load demo
7. click on one of the speaker names, and select a new one
8. watch error in console

What is the expected behavior?

To not get a console error message when using select in the WrapperBlock

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

initially noticed it in 0.10.5, then updated to 0.11.1 but the message persists.
