ContentState.replaceEntityData does not cause DraftEditorContent to re-render

What is the current behavior?
When using contentState.replaceEntityData and then pushing the resulting EditorState, DraftEditorContent component does not update.

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:

The way I did this was creating a custom 'atomic' type block with an entity, and then updating the entityData. I have not tested this with other block types.

(Note that after hitting "make me blue", the next time a change - such as typing in new characters - triggers a render(), the text is indeed blue)

What is the expected behavior?

In shouldComponentUpdate for DraftContentEditor , prevContent !== nextContent is returning false when applying contentState.mergeEntityData.
I would expect either the resulting ContentState object to have changed, or for their to be a separate check that looks at entityData (this seems like it would be more expensive).

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

Draft: 0.10
Browser: should be any, this is a code issue

This is actually the expected behavior currently, but it will be fixed in a future release, see e.g. #1047 for some more info.
