Nested Editor causes exception

[slava-osipov-qs]

Do you want to request a feature or report a bug?
I'm not sure. I think it is a bug, but fix might require new feature.

What is the current behavior?
In custom block renderer of outer Editor I add component that uses inner Editor in readOnly mode. Inner Editor is initialized with some content. When user click to the content of inner Editor then exception occur within getDraftEditorSelection of outer Editor. Draft can't found selected (in inner Editor) block in state of outer Editor.

If the current behavior is a bug, please provide the steps to reproduce...
Please ask for a sample, if description is not enough - I will prepare demo project.

What is the expected behavior?
No exception excepted.

Which versions of Draft.js, and which browser / OS are affected by this issue?
Draft 0.10.5. Running in Chrome 64.0.3282.186 (64bit) under Windows 10.

Did this work in previous versions of Draft.js?
I don't know.

Note
I guess author of #527 was right when mentioned global.getSelection. And my issue caused by context mess.

Would you please provide us with a code sample, error message, etc.? As far as I know, a lot of Problems can occur, when using more than one editor instance or even nested as Plugin into an editor instance in one view. Is that your case here? I would claim, you should care about the focus.

This issue isn't very actionable at the moment - we don't really provide much support for nested editors so you're kind of on your own to hack around any problems.

We're currently exploring a new data model backed by a tree structure (i.e. nested data) rather than a list of blocks & I believe that it may be able to eliminate many use cases that need multiple/nested editor instances. This feature is still alpha & experimental at the moment, and we don't have a clear timeline for when it will be stable.
